Vintage Creep
Smash Master
Imho, there's totally going to be a third Mario stage. Hopefully a retro one, maybe from Mario World? Or Mario Party/Kart?I'm pretty meh about the new stage. I might need to see more images of it or see some gameplay of it in action. I kinda would of preferred a different Mario stage but I guess this is fine if a lot of others are hyped for it.
Also, the inevitable Wario Ware 2 plus the probable Luigi's Mansion stage (maybe for the WiiU version they'll bring back the Brawl one).
