The Kid Icarus Uprising boss music is in fact in the game, Sakurai doesn't disappoint there.
MIDNA IS AN ASSIST TROPHY! SCORE!!!
Ridley (or Meta Ridley?) is apparently an Assist as well, but we saw only a shadow.
Yoshi, as expected, is adorable.
Charizard dumped the dead weight that was Squirtle and Ivysaur. Well, he WAS the main reason I used PT, but it didn't make me suck any less when playing as him. *shrugs*
Greninja is a F*@#ing tease, since I honestly thought the shadowy figure charging up was Mewtwo. Oh well, I can't argue with ninja frog power.
X, Volnutt, Hub, and Geo all join in for Mega Man's Final Smash. No Zero, no Biometals. I'll miss Aile, but I'm damn well not complaining about a Legends reference.
Spark Man remix = awesomeness.
Still hoping to see some sign of Daisy and/or Mewtwo. Even if it's Assist (though Mewtwo really SHOULD be playable, I don't know if there's room for him since we've got four 'mans without Jigglypuff).
Oh yeah, Zero Suit Samus got jet heels. Because apparently she wasn't badass enough.
