Yeah, I knew yesterday, but it is pretty awesome. It's also been pushed back to February, but eh, I can certainly wait. Tails in the game would be awesome as well, but it probably won't be as a playable character. Metal Sonic/Final Robotnik from Sonic 2 combo needs to be a boss fight for the adventure levels.
Little Mac should be in there, he seems like a clever choice.
Also, a Lost Vikings assist would be awesome if when they appeared, Olaf would stand in front of you and block, Baelrog shoots an arrow that stuns, and Erik does a head charge to smash attack any opponents in the way. It would all happen really fast, like, "oh crap it's Olaf... agghh stunned SMASH AH CRAP BLASTING OFF AGAINNNNNNNNN!!"
