I tried various VR, AR, 3D glasses (shutter, anaglyph) and autostereoscopy displays in the last 20 years.
There were several hypes and fads (like 3D TVs and movies) and VR glasses seems like another fad - especially as soon as more and more tried them and cannot imagine to use it for general purpose gaming - it's more relevant for niche topics. Autostereoscopy displays and AR might get a broader audience in future. But current prototype AR devices like HoloLens are a far cry what would be possible, and at the moment a lot of demos are faked to hype unfinished devices, as the reality is that AR is won't be ready for another 3 years (e.g. http://www.heise.de/newsticker/meldung/Microsoft-HoloLens-im... ). A problem of VR and AR-prototypes is motion sickness, that some people have (from my experience often people who have not 100% eye sight) - I never got motion sickness, but I saw some fellows vomitting on the lab floor (carpet).
Autostereoscopy displays like in the Nintendo 3DS handheld console have its appeal as there is no ugly glass needed and technically it's possible to support a group of people, instead of just one person. So in near future our smartphones and TVs may have such a 3D display. And given a 4k LCD panel one can still get a 1080p or 720p 3D resolution out of it, that's already enough and it will be cheap. And with back projection technology even projectors could be used for 3D autostereoscopy.
