WWE 12 publisher THQ has just updated FAQ page of the game and confirmed that the game will have only one commentary team. The only commentators available in the game are "Michael Cole and Jerry The King Lawler."
If you are a fan of other commentators such as Josh Matthews and Booker T, then prepared to get disappointed as they will not at all feature in WWE 12.
Earlier today, THQ also confirmed that the game will have exit themes for Superstars and Divas, more details HERE.
