You'd think his having a leg in gaming and a leg in VR would create a wonderful synergy. Knowing all the in's and out of both worlds he could have insured great integration of Doom 4 with the Oculus rift - making sure iD was on the technological forefront while the Oculus would have a great demo from day 1.
(see the Leap Motion for an example of what happens when you don't have a good demo day 1)
