Nintendo World Report just ran some impressions of the game and they mentioned a few things that haven't been revealed at the dojo yet. One thing I found interesting is that my theory about Zero Suit Samus' final smash was right, she does turn back into regular Samus after using it. Also it turns out Sonic and Pikachu pretty much have the same final smash (as has been suspected). Also, after reading that, the banana peel actually sounds pretty cool.
