Hmm, if they're trying to put as many characters as possible (game was delayed by 3 months), and DLC is planned, I see 3 cuts from Brawl initially : Squirtle, Ivysaur, Snake. Those are the only three that seems extremely likely to be gone.
There's been 32 announced (Pac-Man, Sonic, and Megaman will be unlockable)
4 remaining starters:
- Wario
- Meta Knight
- Ice Climbers
- Lucas
That gives 33 starters... with 17 unlockables on initial release.
Unlockables:
- Ness
- Captain Falcon
- Jigglypuff
- Mewtwo
- Ganondorf
- Falco
- Wolf
- Mr. Game and Watch
- R.O.B.
- Sonic
- Megaman
- Pac-Man
- Chrom
- Shulk
- Marshall (Chorus Kids)
- King K. Rool
- Ridley
13 DLC characters:
- Paper Mario
- Bowser Jr.
- Ivysaur
- Squirtle
- Dixie Kong
- Impa
- Krystal
- Roy
- Takamara
- Mach Rider
- Chibi-Robo
- Issac
- Snake
63 slots, 1 random=64. Any cut veterans would likely be DLC. Roy might come back as a nod to Melee... although Pichu might come back as a joke.
If they're making DLC, the characters better be between 55 to 70.
