That's just the composer, and he has worked on many other games... that list is strange. For instace, Motoi Sakurai, whose work on Xenosaga and Baten Kaitos is awesome, is listed as "Golden Sun and Mario Golf."

Those are good games, but when it comes to music, who cares about Mario Golf? How can them ignore Baten Kaitos' magnificient orchestrated soundtrack, and Xenosaga's, too?
(if you haven't heard BK's OST... eh.... I'll upload a song for you later).

And actually, Power suit Samus has been confirmed - in the old site (before relaunching) in her character page, it said something like "Don't worry, you'll still be able to fight with Power suit Samus, but in some events Samus will strip her suit"

Perhaps it'll be a character like Princess Zelda in the old SSB:M, where she could transform into Sheik and back to Zelda. It'd be pretty cool, since I love double-characters.

I'm all for the Gotwoot Brawl. I'll get my ass kicked, 'cause I suck, but it'll be pretty great at any rate!
