While there is no doubt that physics are going to play a big part in future gaming I don't think Physx is the way to do it.

Most of the games being developed are small and inconsequential, Unreal 3 seems to be the biggest.

What Physx needs is a killer app made exclusively for it. Any game that can run on normal hardware like Unreal is just likely to have bits of Physx stuff bolted on and so the overall effect will be under whelming.

Cell Factor tried this but conveniently left the game out of it.

This combined with the price and overall poor performance of them at this current time makes them an overall very bad purchase. Half the price, double the performance and number of A1 games support and I may change my mind.

With the advent of dual core and soon to be quad core CPUs all this stuff can be done on CPU while ensuring compatibility due to common hardware.
