The game was originally intended for Summer release — no more.

"The additional time will allow the Development Team to focus on ensuring overall high-quality throughout the game by continuing to tune, balance, and maintain the kind of polish that an important title like this demands," a press release notes, "and ultimately providing fans with an unrivalled classic Sonic feel." We can get behind that.

We've embedded a new trailer for the game above. Sonic - 4. Still seems weird. It's looking good though. The running actually looks "right" this time.
