sorry for being rude. Why I think it is crap (and will remain so)? First of all, main problem of VR is not going away, because it has nothing to do with technology per se, since it is inherent problem. VR is after certain time (varies for individuals of course), causing nausea, because VR is incapable of delivering information, which our brain needs to process the picture which is coming through the eyes. It is not tactile, it provides no clue about distance of the objects, nor is providing any refrence points brain needs to create spatial orientation. Just like when human finds itself in zero gravity for longer period. It takes some time to adjust to the fact, that reference points are floating and it that there is no up or down as reference point. But, after some time almost everybody adjusts - and here comes another but - the space (meaning the interior of space vehicle or station) is real with real coordinates and real objects. So eye and brain are able to find some fix points for orientation. VR, regardless how good, will never be able to do that.
