I have the Blue Ray set already, sprite comic included.
I hear they aren't allowed to call Sonic's world "Mobius" anymore, (hence why it's nameless in the movie, and other media like "Sonic X") but I still sometimes refer to it, as such. Wouldn't mind seeing more of "Mobius" in the sequel, as well as the creation of Metal Sonic, and the Death Egg maybe, like the "Death Egg Saga" in the games/comics. (Seeing as we're getting Tails, it'd be a good opportunity to build on concepts from the games.) @northern haste
Just hope it's not "too fat," so he can still do Eggman's goofy overdramatic poses, and gestures.
The Sonic'06 size/pot-belly could work.
