Even a launch game like Kameo was said to use up up to 83% of potential CPU cycles on the 360. With some optimisation and pushing more horse power out the 360 you can still achieve quite a bit more, but current exclusive games like Mass Effect and the high profile Halo 3 aren't technically challenged for no apparent reason. The 360 is hitting its bottlenecks, not caused by still immature game engines.
Gears of War isn't easily compared to GTA IV, GTA povides a huge open world and Gears provides a linear gaming experience. Of course Gears looks good, but it's also a slow moving game and I really had a feeling of being trapped moving around in a glass box environment right from the start on the 360.
