Will I regret buying Killzone 2 PS3 if MS made better games given the time?

Halo 3 took around as long as KZ 2 with a similar budget. And it doesn't look as good, nowhere near. And if MS did ever make something like KZ 2, I don't see why you would regret getting a PS3, just get a 360 as well. And yes, the demo really is incredible.
