Sorry if this is old, but I noticed in the picture when it shows all 32 of the participants, Zelda's tiara is purple, Pit's Olive leaves are white, and Bowser's green.
Meaning, that we know some alternate costumes!
Just something neat I noticed.
Nice find! Also, Peach's crown is pink!
Alternate costumes in some shape or form are pretty much a given, if they didn't have them, only one person could pick each character, which in certain cases, would kinda suck, particularly as you couldn't face 3 of the same character in verses, which I did a lot for fun.
Well, I meant it as in, the kind of colors the characters are gonna be.
My guess is they'll be the same from the last game. I prefer we get big costume changes.
