Now, here's another question that I have; what if we are to receive a roster size of 60 playable characters? Theoretically, of course? Well, I'm here to speculate on what the remaining veterans and newcomers could consist off--let's assume then that that's 12 veterans and 12 newcomers remaining. So, I'll be honoring both sides of the same coin by tackling a top 12 most likely of each based on evidence both in and surrounding the game of a particular character's presence as a playable character. Starting with the veterans:
1. Mr. Game & Watch: The drawing early on in development and his unofficial confirmation in the Pac-Man trailer.
2. Wario: Same drawing, the Ashley and Waluigi ATs, the Wario symbol on them, and the recent leak from the Nintendo eShop confirming him.
3. Meta Knight: The return of Halberd as a retro stage on Wii U, and his appearance on the same drawing as G&W and Wario.
4. Ness: Franklin Badge and Mr. Saturn--specifically the latter. Sakurai also intends in holding on to the original 12 no matter what.
5. Ice Climbers: The polar bear in Smash Run, and Sakurai mentioning them in the interview talking about the difficulty implimenting them on the 3DS version.
6. Falco: The Great Fox stage had two Arwings in the potd, and the Treehouse people had let slip at SDCC a "stun mechanic" on one of the Star Fox blasters.
7. Mewtwo: When Pokemon X & Y was being promoted, when the Gamefreak employees were asked about Mega Mewtwo Y and his possible inclusion, Sakurai answered from the audience, "We are thinking about it."
8. Ganondorf: The Gerudo Valley stage appears to be Ganondorf's home stage on the 3DS.
9. Lucas: The Franklin Badge and Mr. Saturn could also hint towards Lucas's return.
10.Wolf: The "stun mechanic" in the Falco's hint can also hint towards Wolf.
11.Jigglypuff: Aside from a desire to bring back the original 12, absolutely nothing.
12.R.O.B.: Nothing, really.
With the exceptions of Mewtwo, and Lucas (who are 70% and 50% respectively), I am guaranteeing all of the remaining veterans above for a return at 100% likelihood. Yes, even Ice Climbers, Falco, and Wolf.

And now, here's a list of the most likely newcomers based again on evidence in and surrounding the game:
1. Ridley: His shadow being teased during the boss segment in the Smash Direct; his name not being mentioned; the Trophy Quiz theory; Ridley's theme playing when Ki Hunter's trophy came up; the complete lack of Pyrosphere on the Wii U demo; and the fact that we've been teased of his presence since last year when Pyrosphere was shown off as a potd. 100%
2. Shulk: The rumored Mechon trophies found in Smash Run; Adam Lowden coming forward about the voice over work he completed for this year but can't yet tell us; and Monolith Soft constantly retweeting any and every news surrounding Smash Bros. Suspicious much? 98%
3. Dark Pit: He was revealed at the end of Palutena's trailer, and was even shown in Palutena's cover art separate from Pit. The fact that the trailer ends on a cliffhanger clearly means that we are not supposed to know Dark Pit's role until after launch. 88%
4. King K. Rool: Yes, the Kremlings in Smash Run argument as usual. But that's not all, really. The lack of an original DK stage, and the fact that almost four whole months have passed without any clarification regarding his role helps support his case as a playable character. If you think time isn't his friend at this point and time, consider too that I originally had Takamaru on this particular list of most likely newcomers last Saturday at SDCC when his game was announced to be coming out on VC worldwide for the first time ever. And he was quickly disconfirmed as being nothing more than an AT two days later. 80%
5. Chorus Kids: The Sneaky Spirits are in Smash Run as enemies. Every enemy found in Smash Run either has a corresponding franchise represented by playable characters, or originated from Subspace Emissary back in Brawl. They may not hint at them specifically, but at the very least, we're pretty much getting a Rhythm Heaven character. 70%
6. Ghirahim: Considered switching his placement with Chorus Kids, but decided against it since the Trophy Quiz theory is just a theory. But, given the trophy was of Fi from Skyward Sword, but the theme that played was Ballad of the Goddess, which is Zelda's Lullaby in reverse. Actually, given the fact that the Trophy Quiz theory highly suggests a newcomer from Skyward Sword, and we have two polarizing attributes (Fi in relation to Ghirahim, and the music to Impa), I ultimately decided on Ghirahim as the SS rep by virtue of the fact that Impa could very well turn up as a Sheik alt. 65%
7. Paper Mario: I was waiting for some concrete evidence that could support Paper Mario's inclusion as a playable character, and apparently, the Paper Mario stage on 3DS is just what I was looking for. All we need now is a Paper Mario stage on Wii U, and I'd consider his conclusion fairly locked on. 55%
8. Dixie Kong: This is mainly the backup to King K. Rool in case the latter doesn't pan out as a playable character. Because frankly, there's no reason not to have a new DK rep at all. While lacking in evidence so far, she has Tropical Freeze to apparently back her inclusion up since she has "recency" and "relevancy" on her side. The question is, is she too recent? She is also one of the Forbidden Seven, but since she was meant to be paired up with Diddy Kong similarly to Ice Climbers in Brawl before being cut since "it wasn't going to work," I really cannot use her exclusion as evidence in her favor (heck, at least Roy and Mewtwo almost made it back in). 50%
9. Excitebiker/Mach Rider: Excitebiker simply because he was going to be playable in Melee, but because Sakurai couldn't figure out a believable way to make him jump, decided to instead go with Ice Climbers as a retro rep; this could change. Mach Rider is simply the more believable forgotten retro rep for this game, but I'm keeping my options open. 30%
10.Duck Hunt Dog: No evidence, really. But it does seem to be the most logical follow-up to the likes of R.O.B. and Mr. Game & Watch for the retro joke character whose role in the video game industry proved vital (after all, the game came packaged together alongside Super Mario Bros. on NES). 25%
11.8-Bit Mario: There's evidence, during the amiibo segment of the Digital Event where he, Lucina, and Mr. Game & Watch were all shown together. What they all had in common was at the time, none of them were confirmed for Smash 4; we have since gotten teased further with G&W, and Lucina has joined the battle as well. Granted, there were a few characters on there like Isabelle and Tom Nook who were all disconfirmed long beforehand, so maybe this may apply with 8-Bit Mario as well? Regardless, 8-Bit Mario is the only character left on here who hasn't been confirmed or disconfirmed either way (and yes, Mario is there, too; so I'm not overlooking any obvious details, here). 20%
12.N: Really, the only valid reason I even have to add him as a potential newcomer is due to how coy Sakurai was in the potd revealing N's Castle as a stage. At the very least, I can safely expect him to make some sort of appearance on the 3DS version of the game, but in what role? I have no idea. I'd be very excited if N turns up to be a newcomer. I don't think he will be playable, but I'd be very surprised (pleasantly, of course) if I'm proven wrong. Less than 1%
I'll probably update both of these lists as time goes on. But for now, we'll just wait and see.
