According to IGN there is a demo this week for PS3/360. You can only play exhibition but you get UFC and Pride organizations. UFC will have Anderson Silva vs Jon Jones. Pride will have Rampage vs Wanderlei Silva.
Odd that they give you Anderson vs Jones considering they don't fight in the same weight class (yes I know Anderson fought LHW a couple times but that was it). I get tired of the superfight talk BS because it rarely happens. Seems like most people are finally over the GSP vs Anderson talk. In the past, they gave you 2 fighers that had a fight coming up.
