I'm thinking we'll have over 10 reveals, probably most of the Brawl roster will make it back, except about 5 cuts (this includes Squirtle and Ivysaur). Meta Knight will make it back by fan demand, but hella nerfed. A Fire Emblem Awakening character will make it into the game in some playable form. Mii will be revealed. Pac-Man, Palutena, and the Choir Boys will NOT be revealed, thus ultimately proving that supposed "leaker" to be nothing more than a lucky guesser whose luck ran out. A Namco character WILL make it in, however, but it won't be Pacman. Ridley will only be a stage hazard, in the same style as the yellow devil.
Dream Announcements:
TONS of alt skins bring in characters that wouldn't have made it otherwise, like Dr. Mario (Mario), Daisy (Peach), Lucina (Marth), Chrom (Ike, if Chrom isn't his own character), Roy (Chrom, if Chrom is revealed, otherwise Marth), Lucas (Ness, if Lucas doesn't return as a unique charater), Falco (Fox, if Falco doesn't return as a unique character), Toon Zelda (Zelda), Young Link (Toon Link), Pichu (Pikachu, this time without damaging itself), and Shadow and Amy (Sonic), and they'll all have unique, but mechanically the same animations, and their own voice acting.
Krystal is revealed, with her staff. Fox, Falco, and Wolf are also playable. They each have their own unique Final Smash. Fox still has the landmaster, but Falco has the Arwing, approaching like Snake's helicopter did in Smash, allowing Falco to shoot the field from a distance with lasers and bombs, and Peppy warns him to use bombs wisely. Slippy makes an appearance too I guess, as a quote like Peppy, and thus the whole Star Fox team is in the game. Krystal can uh...ride a dinosaur I guess. Wolf can...shit this is hard.
Ghirahim is revealed. Final smash is Demise. Enough said.
I'll dream a bit bigger than Smeags: Knuckles is revealed. He's as bad in the air as Little Mac is, is about as strong on the ground as Little Mac is, is almost as fast while running as Sonic, but his attacks are slower than Brawl style Oldmanondorf, and to make up for all this, his side+B is his glide, which works like it does from the games, and he has the ability to climb walls, like in the games, thus giving him the best recovery in the game by a long shot. He has an alt skin that makes him into his super buff redesign, just for shits and giggles.
