The PC and 360 have similar hardware infrastructure. The PS3, specifically the Cell and its SPU's, take quite a lot to develop for, both in terms of money and team size. And they couldn't easily port it from PC to PS3, they'd have to build it from the ground up. This would be very expensive and it'd take a lot of time and energy, thus it's not worth it for the rather niche audience that would be buying it.
