What about those just wanting to get a previous gen model for cheaper or a used one that can be cleaned up and hacked?
While I understand the whole wait out for something better mentality, aside from the fact that something is "always" going to be around the corner, making waiting for the next big thing a futile effort to forever talk yourself out of ever buying any kind of technology, the aspects of waiting for Valve or other VR folk is not going to offer something that we all want to have, and that's affordability. Hell, even first gen Vive headsets are still pricey as hell and they require you to still be hooked up to your computer to do anything. The preowned market for VR is still all over the damn place, but waiting for the newest thing does not seem to benefit anything in terms of price or value. Either have $$$$ to spend or luck out in the lottery in buying a preowned unit for cheap whenever it happens.
