Xbox 360 vs. Ps Triple Gamez?

I own a PS3 and am pretty confident that the system will earn the respect it deserves. It really is a powerful piece of hardware. Only if game developers can fully utilize it. But right now, I would have to say that the Xbox360 has the advantage. BioShocl, Halo 3 are both amazing games. Heavenly Sword for PS3 was a bit of a let down. And seeing as how many top games like GTAIV are going multi-platform, I might have to invest in a 360. I am willing however, to give the PS3 another 6 months before I decide on buying a 360.
