Sukapon
Chance: 3%
I think Sakurai acknowledges Sukapon, but I don't think he is entirely interested in Sukapon. He has everything to make him viable in Smash thanks to Joy Mech Fighting, but even with that being said, I doubt he will go over other retro characters like Takamaru.
Want: 30%
He would be cool to have as a limbless fighter, but I rather have other retro characters, like Takamaru, get on the roster before him. Sorry Sukapon, maybe Smash 5.
Little Mac
Chance: 95%
I am this sure that Little Mac will be in the game! Punch Out!! started as an arcade game (with a sequel, Super Punch Out!!, and a spin-off game), but Little Mac made his name with Punch Out!! for the NES where he and his game became pretty popular. After Super Punch Out!! though... he fell off the radar for a long time. While he appeared in Brawl as an Assist Trophy, he became a mostly obscure Nintendo character (as shown by his appearance in Captain Rainbow). But, Little Mac rose once again with Punch Out!! for the Wii getting a good amount of sales and even became a part of Nintendo Selects. So, Little Mac has a major history as a part of Nintendo.
History aside, I think his series' resurrection helps him because, again, it made him more popular. Not only that, but Little Mac is a highly demanded character. While he isn't wanted as much by people in Japan, he is highly wanted in the US! Just because he is wanted in one area doesn't hurt his chances since a majority of the people who wanted Pit in Brawl were people from the US. Numerous fans and critics want to see Little Mac enter the ring before Brawl and now before SSB4. However, I don't think his chances in Brawl are nearly as strong here. It has come to the point where Little Mac is an incredibly hard character for Sakurai to ignore and he has to feature him in the game somehow. In fact, I think Sakurai has mentioned that he likes Punch Out!! and he even called Little Mac "legendary" on his Assist Trophy page on Brawl's Dojo!! website. Little Mac does meet the requirements for Smash as he is popular and would bring in a new fighting style to the Smash series. While we have seen boxing styles in other fighting games, we've never had a boxer in any Smash game.
I should also mention that boxing arena stage. I always thought that it was odd that there wasn't one until now... and now I think that it's the home stage for Little Mac. As I was in the original Rate Their Chances Returns thread, I found a link to this post in the Little Mac thread:
The boxing stage might as well be a Punch Out!! stage.
All in all, I think that it comes down to if Sakurai wants to have Little Mac in the game and why wouldn't he? Again, he is an incredibly hard character to ignore at this point and he would generate a lot of hype! Maybe not the same level of hype Mega Man brought or Mewtwo would bring, but still a lot of hype! Also, I don't believe in the leak, but I think he's going to be in the game regardless.
One more thing. If people think that Little Mac is de-confirmed because of this image:
Then I totally disagree with you. Just because the Villager is using boxing gloves doesn't mean it's a direct reference to Punch Out!!. I think that it would be if those gloves were green like Little Mac's.
Ultimately, it comes down to Sakurai. There's so much going for him. Though, to be honest, this is probably the best chance he is going to get. If he doesn't get in now, then he might have trouble getting in SSB5 and later installments.
Want: 100%
I probably would have given Little Mac an 80% want before the DDoS. However, I found a copy of Punch Out!! for the Wii and it made me want Little Mac more and more! I love that game and it's an incredibly fun puzzle game! I loved that game so much that Little Mac instantly became my most wanted newcomer for SSB4. He just fits in so perfectly with the cast and crew of SSB that I would honestly be heavily disappointed if he wasn't playable. Heck, he would probably be one of my mains! I don't care if he is Meta Knight good or Ganondorf bad, I would still play as Little Mac often!
Whew... finally got that out of my system.
Sorry for the long post!
Andy Prediction: 7.25%
I think that he does have a chance. But, we haven't seen him in a long time... I bet some will give him 5s and 10s.
Nominations: Captain Rainbow 5x
EDIT: I just noticed something on the nominations list:
X12 Amaterasu (Okami)
X5 Ammy (Groose doesn’t know)
Groose, Ammy is the nickname for Amaterasu from Okami.
That nickname was given by the character Issun in-game. So, Amaterasu should have 17 votes. Any time you see "Ammy x*insert number here*", give those nominations to Amaterasu.
