It's beginning to appear clear that FPS is VR's pipe dream. The locomotion part seems non-trivial to solve and dissonance between the virtual and real world renders VR FPS completely unplayable for a large amount of gamers (it can make you feel incredibly uncomfortable, can also cause motion sickness.)
HL3 and Portal 3 would be incredibly difficult to implement well in the VR space, and I feel this is something that Valve understands much better than many others.
