I still think interaction is the major shortcoming and probably will be for the foreseeable future. Most of this seems to be a technology-psychology hybrid. I want to grab a virtual coffee mug with sufficient feedback so I don't grab through it, feel the weight of it etc. Another part is finding good interaction paradigms which I suspect will fall out of better technology being available and in more hands (easy to prototype interactions). Wide spread first gen VR-Headsets and primitive interaction means (controller) will probably be good enough to drive that.
