And just exactly could he have improved the performance significantly ? 

Lots of "little" things could always be improved, like culling and compression techniques, rasterization is actually extremely wastefull.

I don't expect "next generation" levels of graphics on last generation, but they could still see some gains and that may happen, it's not over for those old antiquated platforms just yet.

Culling and compression is pretty much as good as it gets. There's alot of games that use extreme forms of culling such as occlusion culling and compression ratios go as far as 4:1 for 32 bit colour space. Last I heard rasterization is waaaaaay more efficient in comparison to ray casting or ray tracing and other monte carlo methods to rendering.
