I play as Pitt, Ness, Bowser, and Jiggs.... Jiggly Puff is the only chracter that has a chance of not coming back, and I might start playing more as Samus since she seems a lot faster, and Megaman looks awesome.
I hate the idea of cuts though... I really like playing as Wolf from time to time, for instance, but am not a fan of Falco or Fox, so if he is taken out there goes a character I enjoy.
