Well, sure it's free, but how many players will be there online compared to the 360 scenario? All of my gaming friends have both systems, and they end up buying 360 versions of all the multiplatform games because a) the do look/play better or b), if differences are "minimal", there is still that little thing called GamerScore they want to feed (this is a huge hook for them, clearly the best feature Microsoft could have come up with this gen. But this is beyond the point). So unless PS3 versions of multiplaforms, online-centric games are at least IDENTICAL to the 360 ones, they will keep buying the latters. Which "forces" me to do that as well in order to play with them online.
