VR is too small of a market to support a AAA VR-exclusive game.
most vr games will be indie level and therefore ps4's "lack of power" won't matter because the game won't be all that advanced to begin with. i think most games will target ps4 and then ported to pc because i don't think any developer is brave enough to be exclusive to either platform.
...except sony. sony will bring a few exclusives to their platform making it the defacto better supported platform.
