It's a shame the multithreaded software isn't coming out as fast as the hardware - I'm sure the games compnaies will start to produce more 'Quad' titles now they are learning to programme the consoles.
It's not a matter of what they know how to program. Game companies develop games for the hardware that their customers will have; there's no point developers aiming for an octo-core 5GHz CPU if 99% of their sales will be to people with single-core 2GHz CPUs.
As a result, games are almost always a couple of years behind the hardware. They might have a 'bells and whistles' mode that adds extra eye-candy for fast systems, but standard gameplay is almost always going to be aimed at hardware from 2-3 years ago.
