User blog comment:'Sonic the Hedgehog'/What would you like to see in my new game, Sonic Generations?/@comment-3295259-20110807055456/@comment-3201026-20110809203752

And for Time Eater, I'm guessing its a robot made by Eggman so he can go back in time. It's supposed to be a celebration of Sonic and it would be strange to have the final boss being someone besides eggman.
