What advantages, besides standardization, does WebVR bring to the space?
VR is still a relatively high-performance 3D realtime application space. Those aren't generally adjectives I associate with either "JavaScript" or "Browser," so if I were trying to invest in an experience the average consumer will enjoy, I'd be extremely skittish about this tech stack unless I can see some successful high-performance demos.
WebVR advantages: open (not owned by a single entity), connected (travel from experience to experience without having to close and open), publish a web page in ten seconds vs. one month (six months for Oculus), no installs / downloads which is better suited for long-tail content, ability to be responsive / gracefully degrade (for better or worse).
