I don’t know - mobile phones were a huge huge success because they are first and foremost, practical. They fit in your pocket, can take stellar images, have access to literally everything on the internet and are fully capable general purpose computers in your hands - a sci-fi product turned into reality. And on top of that, we control them with our hands, which are arguably our most capable part for this job.

I don’t see any practicality to VRs outside some tiny niches. They make a few games more fun, some niche workloads can be done more efficiently, but they are hard to equip and first and foremost block your interactions with the real world. Sure, some contact lens futuresque thingy could improve on this as well, but how would you control that? Voice control is slow and troublesome.

So I don’t predict a huge success to VR, it will be at most something akin to an xbox’s kinect, or some wii accessory.
