First isn't it a little weird that Chuck Liddell and Rampage are in trailer?
And second, the trailer is fake, that was the trailer for the UFC game that was suppossed to come out it 2007-2008 but was canceled. Sorry, to burst your bubble, but Undisputed isn't coming out this year. Instead we get 'UFC Trainer' a motion control game for Wii and Kinect. Undisputed is getting a reboot in 2012 and I asume that is because UFC probably wants to include SF in the game.
