Sony has finally announced the price and availability of the Playstation VR. It will be $400, coming in October. This compares with the Oculus Rift for $599 and HTC Vive for $799. Moreover, the Oculus Rift and HTC Vive require very powerful PCs that can be very expensive to upgrade if you don't already have the hardware for it. By contrast the Playstation 4 is available for $350.
Why is this important? Because when people buy the PSVR, they will want content. And you don't necessarily have to be a game developer. You can buy a 360 camera to produce 360 photos and videos. Remember, the PS4 has over 35 million units sold. If even a fraction of those players get the PSVR, it will dramatically increase the demand for 360 photos and videos!
