I hope not, if used in normal stages it kind of overpowers Sonic furthermore if used in a final boss level again then it just goes to show that the 'Sonic Team' had run out of ideas.
I hope they do something new (but this post I did right now is really biased, I haven't even played Sonic Colors yet I watched the Wii game play). They're probably going to stick to originality therefore they might just put Super Sonic into the game...
