I don't follow consoles anymore, but the last time I checked only six cores were available to games, and Microsoft had just freed up part of the seven core to game devs under certain condition (Kinect and other stuff disabled).

Moreover it is good to differentiate cores from threads. Jaguar cores are single-thread.

Last core-load diagrams I saw months ago showed recent games loading six-core (six thread) Piledriver >90%, octo-core Piledriver >80%, and six-core (twelve threads) IvyBridge loading dropped to >60%.

I am convinced that most of PC gaming in next years will not be made on octo-cores (16 threads), but on quad and dual-cores.
