I don't think they really care all that much. I am well aware of the fact that a large ammount of Multiplatform games are inferior on the Ps3 and have graphical and framerate issues etc. But the Ps3 has some good exclusives, and I think Ps3 owners care alot more for their exclusives like Uncharted 2 etc. which all use the console to its best ability.
The Ps3 is just harder to program for and Third-party developers tend to shy away from it or don't invest as much in it as Sony owned devs do so they can't really get the most out of it.
I am not going to argue with you. It will simply be a waste of my time, and yours.
