Take your fingers out of your ears (eyes) and actually read what people are saying to you.
The added CPU power is minimal. It is mainly being used up by the OS enhancements, which include REAL-TIME EYE-TRACKING to negate the 3D ghosting effect. That shit doesn't come for free and the system will reserve that bandwidth for that feature at all times. Therefore we can expect that very few games will actually be exclusive to the new iteration, and the ones that are probably won't even be localized.
How can we expect few exclusive games? They've already announced three games that are soft exclusive (can be played on old console but requires an expensive add-on) and one full exclusive.
