I know I'm going to get ripped on this, but the point is that it is too early to declare a winner. 
Last gen, Microsoft effectively sold a gaming console with a lower price point and a great array of games (like the ps4 this gen). I have noticed though that many people have said that they started to lose interest in the x360 around the time when the Kinect was sold - as less exclusives were coming out then. What is to say that Sony won't start pushing VR games with a higher priority so that they can recoup some of the development costs of Morpheus, just as Microsoft pushed the Kinect at its time. After all, both were meant to be gaming accessories. The point is that it is impossible to declare a winner yet.
