I don't deny that multi-core will become more and more prevalent, but which if Sony's games use all of the Cell's cores? Last I heard KZ2 uses 4 SPEs, and even then quite sparsely (a lot of idle time on those 4). It was on some presentation slide by Guerilla, unfortunately I can't find it right now.

EDIT - Found it:

 

that depend's on what you are wanting do do with Each core :

example Warhawk's developer stated this:

Incognito's  talking about using Cell to render geometry:

4. What did you do on this game that you couldn’t do on another platform?

It’s hard to answer this and not sound like a gratuitous SONY sales pitch
Although I would say it’s the sum-total of all of our natural phenomenon in the game. Our clouds, procedural water, atmospheric scattering, terrain, etc. All of this stuff runs in parallel on all 7 SPUs simultaneously every frame – I’m still not sure if the game community is giving enough credit to just how fast the SPUs really are.
