Looks cool. It'll be really nice to wash down SM3DL's mediocrity with some 2D platforming. I'm hoping this game has a lot of the stuff NSMBWii was lacking, like taking Yoshi everywhere, for starters.
Also, what's up with the title? Why 2? Why not 3?
EDIT: Just realized something, if in 3D Land the Super Leaf gives you the entire Tanooki Suit, then how do you get just the raccoon power alone?
