There are only 2 Exclusive PS3 games - the other is a PSN title. I don't think this is one though as those 2 games are going to be playable on the TGS floor, and if I'm right I think Level 5 said WKC 2 won't be at TGS except maybe a trailer?
There are more then 2 PS3 games going to be announced anyway, just 2 which are going to be Sony published. One will be the big 'wands' title, probably a new Hot Shots Golf as someone said. The other could be WKC 2 but if it's got to be in playable form I'd say we're more likely looking at something else.
*shrug*.
