Gaming in VR gets all the attention because it is flashy, easy to convey to an audience and makes for good screen shots. But, at least half of VR applications (and probably more than half of revenue) will be in non-gaming applications. Design, simulation and training will be major areas. Sit inside a car while designing it. Walk around underneath Canada while looking for oil fields. Play out your role in the operating room a hundred times before doing it for real.
WebVR is a real thing, btw. It's VR delivered through the web --like video via the web. Between WebGL and WebAssembly, it should at least be able to keep up with the best mobile VR platforms.
