Excellent role for John if that is the case. His work as always been great for showing off what can be done, sometimes I wish he could find a game designer who could drive his engines how he expects it will work but at the very least he can create tech demos to show case how he has helped shaped the hardware.
Also, he has always appeared to want to help the community move forward by using his influence on hardware (birth of 3d accelerators for example). While not everybody would agree with his choices, its still great to see somebody put the effort in.
Good luck to John Carmack and the Oculus team, hopefully the tech will help change the way people interact with computers.
