Via IGN, this footage is from the Xbox 360 build of the game, though I'd like to assume the PS3 version is off from this at all (as that's the version it'll pick up if this turns out good). All I can really saw is wow, I don't think I've ever been as excited for a sonic game in quite awhile, even the music is catchy for once, instead of that mostly annoying, wailing 80's rock. Enjoy!
I'm still very curious to see the Wii version, as it's supposed to be completely different from the rest. And I'm sure no one will care for the PS2 edition. Also, check out the end of the video, seems as if a logo for the title has been created.
