maybe it is the game that should be the 3rd wiiu exclusive ? 

I thought they said that they would continue to work an another Sonic games for the other platforms, I'm guessing that, is this game. Looking forward to seeing it. I hope it's fast Sonic again, I didn't like Lost World.

Weird. The link seems to be broken to me. Anyway, this pretty much confirms that the 3rd Sonic game went multiplat because of Lost World's crappy sales. Can't blame Sega for doing that.

Surely there will be some mobile games with Sonic?

Sonic Adventure 3!!!!

I'm interested, at least. Lost World demonstrates a lot of potential in terms of getting the formula right, the 3D sections are no longer "auto-run" and the available precision in the 2D sections has increased. The parkour formula needs refinement badly and Sonic Team is starting to get some bad habits in regards to actual level design, but they've got the formula to make something really good soon.

Shadow the Hedgehog 2!  :)

Probably a tie in for the new show Sonic Boom

a publisher actually doing something smart. Good for them.

If you ask me, at this point they have no choice but to make Sonic adventure 3 or Generations 2 or Heroes 2 at this point.

This strategy with different titles everytime is not doing anything good for Sonic.
