GoNintendo.com is going crazy over the possibility that Sonic Unleashed is coming to the Wii and it looks like this:

They also found this info over at SonicStadium.org:

- Sonic becomes afflicted with a curse…that turns him into a werewolf. Sonic will have to battle himself, essentially.

- gameplay includes Sonic and the Secret Rings style running with switches to 2.5D platforming thrown in

- Sonic will transform at certain points in the game, and his new form will include some sort of new mechanic

- another new character will be introduced

- Sonic Unleashed is not the final name, and no platform(s) were mentioned. File names of the original leaked images indicate a multiplatform release of 360/PS3/Wii

So is this the real deal or a big hoax? Either way, this footage looks nice as also seen on GoNintendo:

They are awaiting official word from Sega as to what is going on with this. Still almost a week too early to be April Fools.. No one’s even sure if it will be a Wii title but it sure looks like fun.
