Because John Carmack is the guy all video card manufacturers, especially ATI
and nVidia, go to during development. If you read his .plan updates, you'll
get a feel for this. The fact that E3 is about upcoming software, not
hardware, means that no NV30 technology was given to the D3 booths at E3, so
they had to use the best available hardware to get a decent framerate, maybe
spend a week writing temp optimisation routines for the 9700 so the journos
don't get upset.
Remember glQuake? id Software supported 3DFX, and so all the other
developers did, and so all the customers bought one. PowerVR missed out,
despite being better and cheaper. Now JC is the guy you need to impress if
you want to be a successful video card company. Surely you knew all this?
