What do we know about "BloodRayne: Betrayal?" Not much, although we're certain it will be better than the movie the franchise inspired in 2006. We know, of course, that "The blood-tastic hack-n-slash side-scroller is coming to both XBLA (August 31) and PSN (August 30) later this summer." How do we know that? Because that's what Jerry, the PR guy, told us.
