I think AR is at least 10 years behind VR in terms of mainstream adoption or "usefulness". VR is almost there (I think with 4k resolution, it will be) to provide incredible advantages over what we have now. AR on the other hand will most likely be mainly a gimmick for the next 10 years or so, even if they can show some pretty cool demos initially. Take Microsoft's Illumiroom for example which is "sort of AR". The immersion is much greater in VR than what Illumiroom offers, and I'd much rather be "present" in a VR world, than see some light show on my walls, at much poorer quality and much lower realism.
