Yeah for sure, Sony is great about cross-platform stuff like Infamous, Warhawk and...wait a minute! Horrible example, if Sony was in Microsoft's position we would get 1/10 games ported and be lucky to get that 1 game.
I think you missed the part where I said "MMO." The rest of the games they published were always
PS3 games, unlike Halo, Fable, Gears of War, Alan Wake, etc, which were once PC games. The difference between Microsoft and Sony is that when Sony does publish a PC game, they announce it right off the bat and make sure it's a consecutive release. MS, on the other hand, denies everything and only mentions the PC version a year after the 360 version.
