UPDATE :
Sonic Boom is the the 3rd Nintendo Exclusive
From SEGA GERMANY :
"Das in Kalifornien von Big Red Button Entertainment (Wii U) und Sanzaru Games (Nintendo 3DS) in Zusammenarbeit mit Sonic Team entwickelte Spiel ist dabei der dritte Titel, der im Rahmen einen Exklusiv-Deals von Nintendo® veröffentlicht wird"
Developed in California by Big Red Button Entertainment and Sanzaru Games in collaboration with Sonic Team this game is the third title, which is published under an exclusive deal of Nintendo ®

Aha! Maybe Nintendo had a slip of the tongue and that 2015 title really is coming to the Wii U but PS4 and X1 aswell as the rumor suggested.

The official site is open.

I still can't get over how out-of-place and just... not... good... Knuckles design is. *laughs*

Seriously. The head just doesnt go with that body. Maybe a bit of neck could fix that... but for now its just terrible.

Edit: I just tweeted Sonic the hedgehog about this Knuckles thing. Not that i have any hope, but we'll see. Aslong as they listen, it shouldnt be that difficult to change the model a bit to at least make the proportions look right.

I've added this to the OP of the NintenDomination thread, is that OK?

Looks better than Sawnik Lawst Wurld graphically at least....

Looks a lot like Heroes. That's the kind of game i've been wanting from Sonic Team for ages, hyped a lot here.

I just laugh every time I see him. He dosen't even portray the "strength based character" from other similar gaming tropes well, instead he looks like a shopped and magnified version of what the character is supposed to look like.

sure
