The problem is that the next generation should have more resolution, which is the main limitation of the current VR headsets. That will probably make them more expensive to manufacture, and require an even more powerful computer... but at the same time, people is waiting for lower prices to buy it. So it's hard to know what's going to happen. The best bet would probably be for HTC to release a Vive Lite with a little less resolution, and maybe without camera, so they can sell it much cheaper and start gaining some market. That'd also lower the computer power requirements. Once there's market they can start slowly improving the specs.
Since GlobusDiablo wants to run ED, I don't think lowering the game quality is the solution. We are all trying to eek out more quality through hardware, pixel tweaks and such. The quality of the game is more in FDev hands and will be aimed at current HMDs for some time I would think.
As for GlobusDiablo's wish for the magic price point, I suspect as more HMD's of current spec come to market (OSVR has just met current resolution) competition will drive down prices. I would not expect the kind of price cut he hopes for, for a year at least. One would think current economic factors will also play a part in Britain. Time will tell.
