I have my xbox 360 hooked up through a toslink cable and ouputs in Dolby Digital 5.1 and games like Gears of War 1/2, Call of Duty 4, Rainbow Six Vegas, Resident Evil 5, Halo 3, Fallout 3 etc etc (the list just goes on and on) sound absolutely amazing and very realistic. I don't have a PS3 but the sound quality would be just as good. Killzone 2 I would imagine would have excellent sound.

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
