Honestly, things seem to be moving in the opposite direction; wireless HMDs (or integrated processors), on-board outward-looking 6DOF tracking for the head/body positioning, plus similar tracking for the hands (no "datagloves" needed) - and ultimately the arms (ragdoll physics + IK)...
Ultimately, people want to wear less stuff to get into a VR world, not more. If the HMD could be ditched (or be made even less obtrusive than it currently is - which is, IMHO, light-years ahead of where things were back in the 1990s) - people might (big if) flock to it in droves.
Still...there's a lack of a "killer app" for VR. Gaming doesn't seem to be it, yet (a large part of this is the "total buy in" dollar amount needed - it's just too much except for the hard-core players, at best). Social apps don't seem to have gained much traction, either. VR porn seems to be a lost cause as well.
If VR can't make inroads with a "killer function" - it likely will just die on the vine for the second time, unfortunately.
