I...I...there are no words...
Completely threw me off guard. Wasn't expecting anything like that. It just looks incredible and the idea is so unique and interesting. I take off my hat to Ubisoft, I really do.
As for platforms, he was definitely using a 360 controller but the graphics, animations and everything looked way better than anything we've seen on the 360 and PS3 so far. I'm thinking it's a next-gen title and was being played on PC with a hooked up 360 controller.
I just hope that if that's the case, it somehow comes to WiiU because the WiiU's GamePad would be a perfect fit for something like this. It really would.
