Due to unfortunate circumstances, the rest of the edits may be later.
Before I start with anything else, I would like to thank my two assistants for helping me with this thread. GoldenYuiitusin and Super Smash Bros. Fan, so questions can also be directed towards them instead of just me, making it even less of a “My roster” thread and more of a community based roster. I would also like to thank Homelessvagrant for making the original thread during Brawl.
Welcome to the Probable Character Roster 1.0! The first version of it, and the only Pre-Smash 4 version. The version will not be updated to 2.0 (Or any further) until we get to E3. This roster in it's Pre-Brawl edition will not have as many edits nor as much detail (and more characters, at first)
First question's first: What makes this roster so different? (At least for now) We're analyzing all newcomers on a large scale that will be edited once a week (I don't have all the time in the world) – I will be putting the edits down below.
I encourage everyone to participate and urge you all to come in here for discussion and debate, and as always, I encourage everyone to stay sane and not jump down to petty insults.
If there's something you don't agree with or have an idea, feel free to tell me. I hope you all enjoy
Before we start, here's a few general rules I'm uptaking:
-Once a Week Rule: I can't update this for every time someone wants to point out something wrong, so updates will be done once a week, with a post dedicated to what's changed and whatnot.
-The Percentage Rule: Just because I have fancy percentage numbers doesn't mean jack. For starters, in the original thread, quite a few unpopular or lesser choices made it in. This is less of a rule and more of a thing. Focus on their placement more in correlation to the color and what I (Along with any future edits) have to say.
-The Japanese Rule: If a character is Japanese only, they'll have a lesser chance of being in Smash 4, as unfortunate as it is.
-The Copyright Rule: Third-Parties are a sketchy one to present and that's why few will be shown on this roster to begin with. It's already hard enough to place a percent on these guys: Making a percent on something that's more “Yes or No” is even harder.
-Flavor of the Week Rule: This applies more to on-going RPG series like Pokemon and Fire Emblem. They may be considered higher because of what I like to call “Flavor of the Week” but at the same time, this holds as a disadvantage (Especially in the case of possible newer games/Overpopulation rule)
-The Overpopulation Rule/Completed Series Rule: This is both a pro and a con. I would like to thank ToiseOfChoice for this one from the first Smash 4 thread. (He can explain this far better than I ever can) While some characters would be able to complete their series, they also may not be included due to bringing the roster up from other series. Also, lesser series are possible to not have more characters than a bigger series.
-Modest Rule: Sakurai's a modest man, so he may not represent his characters much like others.
-”Better seen elsewhere” Rule: This applies to very few characters, but possible contenders may be seen better off as Assist Trophies, Bosses, Generic Pokemon, or somewhere else better in the game.
-The “Programming vs Artist” Rule: Some characters are hard to program, but thankfully, this doesn't apply to many.
- - - - - -
For this version we've got a color code with the pictures:
Blue = In
Royal Blue = Shoe-ins/Highly Probable
Pale Green = Highly Probable
Lime = Quite Probable
Yellow = Decent Probability
Orange = Slightly unprobable
Red = Unprobable

"I must be playable. I MUST!"
We all want him. Who doesn't? Frankly, I'm still a bit shocked he wasn't in Brawl as playable. Being the second most requested character by North America for Brawl, mentioned after Brawl's release, and ranked high up on the Japanese Brawl poll. I had a hard time thinking of disadvantages for this guy, so 95% chance in, and 5% chance for team stupid. Who's with team stupid?
Advantages-I'm actually not considering poll charts too much on this, but his popularity is more than noticeable.
-He would easily bring apart more Metroid representation
-Completed Series (He would fall in to complete his series)
-He would easily bring a character that people would want to play as to the game. He was even memorable as a boss.
Disadvantages
-Programming vs Artist rule.

"I've been waiting for this for a long time. Soon Donkey Kong, and his own Island, will be no more."
I'm actually shocked I'm putting him up this high. High? Sure. This high? Well, whatever, we've got to start somewhere, right? He's been relevant to the Donkey Kong franchise and they've had a newcomer as of last time. With the series making a return (...that was terrible) after Brawl and being one of Nintendo's highest franchises, I can hardly think of reasons to not complete it.
Advantages
-He actually has nothing from Brawl that could close his case any other way. No boss appearance
-Completed Series (He would fall in to complete his series)
-He comes from a series that's more probable to have a newcomer than many of the others, to say the least.
-He's still relevant as of recent games.
Disadvantages
-The inclusion of Dixie in the original seven (Though, tag team)
-He hasn't appeared in the recent games (A very weak argument considering Retro still even commented on him)
3)

Oh my... Here we go. This is always an iffy subject for me, and what's even weirder is I actually called this one being cut. With the base he has for wanting to come back in though, and in Brawl him and Lucario only sharing two moves, I can say I like his chances more this time.
Advantages
-He's still a very important part to the Pokemon series
-With Gen Six showing itself and so far our only icon being a possible new form of Mewtwo (Or something else) I can't see why they would replace it.
-Mewtwo has already shown up in a Smash game before.
-With Pokemon being a big series, there's a pretty big room on this slot
Disadvantages-Programming vs Artist rule
-Flavor of the Week

"...I've got nothing. Not even peanuts."
Why not? Okay... So maybe Capcom and Nintendo haven't had the biggest relations lately. Let's just go over this fast.
Advantages-He was mentioned after Brawl's release. I don't remember the exact mention, but hey.
-He actually started out on Ninetndo, and is continuing (Didn't his releases start with Nintendo's shop first?)
-He easily is Capcom's #1 rep.
-Highly requested.
-Much like Ridley, he would for sure traction interest.
Disadvantages
-The Copyright Rule, once more.

"REPLICA"
Namco Bandai and Nintendo having good partnership lately is also nice, sans the part of "Oh look, Namco Bandai is helping. Joy." I really can't see a character not appearing, especially after stated interest in the Tales series. The question is who?
Advantages-Recent releases (Tales of the Abyss 3DS, Tekken Tag 2, etc)
-Namco Bandai is helping with the game
-Shown interest
-Few Third-Party company opposistion
Disadvantages-The Copyright Rule, sadly.

"I'm just awesome and silent. More silent, but still awesome."
Now here's a character that's worth talking about and still very debatable. He appeared as an Assist Trophy for Brawl and has had one game come out since then along with a hopeful other. It has nice support, and it's one of the very few major fully fledged Nintendo franchises to become playable, but will that be enough?
Advantages-New Series that did manage to make popularity
-he did make an appearance in Brawl.
-The series has shockingly came back (after that long wait)
-He's easily a character that would traction interest
Disadvantages-He has other characters to possibly compete against for new series. It depends on whether the Roster focus is on adding more new franchises or completing certain series.
-Dark Dawn's sales were lackluster compared to the other two, to say the least

"Hey come on, I can have blue hair too. Hair surgery doesn't cost that much, right?
I'm actually shocked he got as far into completion as he did. Well... this character is something. How much does Flavor of the Week rule matter here? And Japan Only with Awakening now? Personally, if this were just me, I could see Chrom/Robin more but hey, he has his fans.
Advantages-He's been in Smash before, and not just completely for a clone for Marth
-He was planned for Brawl and has had pretty big support to return
-He (much like all the other lords) still returns in Awakening
-He wouldn't be that hard to include
Disadvantages-Flavor of the Week
-Only in Japan (Not fully, but his game)

"The Monado... I hope I can figure out the secret of its power one day."
Already close to the the end of the 80's. Shulk doesn't have much against his favor, but not exactly much for either. Frankly, I'm just glad Xenoblade (along with the other two Rainfall's) came to the U.S.. The question is all on the roster.
Advantages-His game for sure did quite well
-He would easily make an interesting character: Heck, his game is already about 200
-He's for sure a more important part of Nintendo's Wii era.
-Easily one of the better chances on a new party character
Disadvantages-Has other characters competing against him. Really, once more, it all depends on the direction of the roster, but I wouldn't be shocked to see this guy at all.

"I'll get you mean man Mario!"
We're getting more and more into heated. Soon we'll be in improbable, won't we? He brings a lot of interest either way to his discussion, but many questions come up for and against him. Let's just see what he has.
Advantages-He's for sure been around in more appearances and important as well. Hell, asides from Super Mario 3D Land and Kart 7, he's in every 3DS Mario game. Honestly... he was actually pretty cute in his Sticker Star appearence for those of you who have played that.
-He's had heavy plot important roles before
-The Completed Series rule (Though this goes both ways)
Disadvantages-The Overpopulation Rule: With Brawl only having four Mario reps, it could easily stay that way.
-Other candidates around.

I finally got myself to picking up a copy of Kid Icarus, which is good so I'm actually decent at talking about some stuff later on down the list. While playing it, she's really the only one that appears up in through most of the game asides from Kid Icarus and holds importance in the first two games (I'm only on Chapter 10 right now so be careful with spoilers; though if something spills I don't mind) but is it enough to pull her in?
Advantages-Kid Icarus has recently revived, and with nothing disappointing in it either.
-A lot of personality set upon one character
-With very few series left to go and even less that have a newcomer to establish from while more are being completed in Smash, it does help her a lot.
Disadvantages-Sakurai's Modesty
-Just because the series is back (Unlike Shulk where he's one-shot or saac's being a series) doesn't mean it's fully back.
-She was in as a Final Smash last time, though, much like the other disadvantage, this really doesn't hold much to her
