There's a simple reason why they didn't do that. It's not their market, they probably didn't want to sink extra time into making the perfect PS3 version instead of the perfect 360 version that runs well on the PS3 because it's not going to sell as well.

Also the 360 uses hardware more like the PC, better to go with 2 out of 3 systems instead of 1.
