OK , so if Sonic is in it, it would only seem right to add more sonic stuff. It wouldn't be right if he only got to play on other people's turf. Right? So Chances are that they will make a Sonic stage. Greenhill Zone anyone? They could remake it in 3D and it would be hilarious to see Mario or even Bowser (lol) hit a bumper And Run superfast through those loops. Pwnsome I tell you, PWNSOME! lol, just a thought though.
