Sonic and Sega all-stars racing 2 has already been comfirmed (called Transformed). So far the rumors i heard from Sonic Dimensions is that it will be Wii-U only, and since i hate the wii, screw it. Probably Sonic Heroes 2 or Shadow the Hedgehog 2 would be nice. Maybe if Sega remade Sonic the Hedgehog 2006 by looking at all complaints from the fans, it could be a pretty damn nice game. The idea's they had at first were very nice (Metal sonic had it's own story and all the other characters from Sonic the Hedgehog 2006 did too).
Thanks to Gackt for this AMAZING sig ^^
