IGN.com has revealed that Forrest Griffin and Georges St. Pierre will be the cover athletes for UFC 2009 Undisputed. GSP will appear on the cover in Canada, while Forrest will grace the cover everywhere else.

IGN also has a story and videos breaking down the multiple fighting styles in the game.

Quick update: I missed this before, but the cover story quotes Dana White saying the game’s release date is May 19. Better than June 2!
