i agree, it does remind me heavily of sonic colors. Which is a nice little nod, towards sonic getting back on the right track after his *cough* rough period *cough* and after seeing the trailers, and the gameplay videos of it it looks amazing. and the 3ds looks like its getting full, if not almost full 3d love. however i believe there may be a demo, as with dream team, the demo was released but on the same day as the game itself. hopefully they wont do the same thing with sonic, but even without a demo i will be picking up the game myself when it releases.
