Ah, I didnt know you checked out Dojo. Yes, Yoshi was announced and is part of the starting roster, with a new move I think? Something about using a launched egg to make him jump higher? I don't know, it's been a while since I played Melee so I don't remember some of his moves, and I never used him. On another note, though it is pretty cool to have Zero Suit Samus, I think she isn't needed. I mean, it shows the true power of her Zero Laser, but I feel like the main reason she was added is for sex appeal, though she does seem pretty badass (super fast and that neat laser whip...thing).

Perhaps you should mention that Zero Suit Samus is not really a seperate character from Samus, but rather a transformation. Also, Snake isn't on your list. Por Que?
In regards to Yoshi, I'm real happy about that. The roster is coming along nicely, and he's certainly a long-awaited addition

Zero Suit Samus is regarded as a new comer on the official website, so I'm classifying her as a separate character.

And in regards to your query about Snake, read the whole post: He's 3rd party, therefore not part of the starting roster!
