The trailer, which carries a voice over from Paul Heyman doing his best Burgess Meredith impression from Rocky, features Tyson being encouraged ahead of a big fight before he gets into the ring with Stone Cold Steve Austin and Chris Jericho.
The stuff with Y2J is in-game footage showing the moves Tyson will perform as a playable character (which as expected mostly includes jabs, punches and a Lou Thesz press) and reveals that his look in the game is from his three month run as a member of D-Generation X in early 1998.

As we wrote yesterday, Tyson will be included in the game as a pre-order exclusive (and probably as a paid DLC at a later date). WWE 13 will be released November 2nd, 2012.
