I spoke about Dana White dropping Jon Fitch the other day because he wouldn't give up his image rights for the upcoming UFC game. That issue aside, UFC Undisputed 2009 actually looks like a pretty good game.
I had UFC Throwdown for the GameCube years ago. It was ok but far from perfect. The new game looks a lot better. Hopefully the game will play as good as it looks.
It's being developed by Yukes and THQ, the companies behind the WWE games the last several years, so it's probably going to have the same kind of feel to it as the WWE games.
Unfortunately, it won't be released until next May. Oh well :)
