Very interesting. IMO, cost will be a huge hurdle for something like this. $149 or bust.
For good VR, I'd actually be willing to go as high as the $300 range. Assuming of course that support is good. It really comes down to price. If Occulus Rift ends up costing $300 and Sony's is drastically more expensive, I'd more likely go back to PC gaming when I upgrade my laptop in a year or two.
