The recent advances in VR are only partly about the tech - reducing latency and weight. Most of the R&D gains, I would argue, have gone to getting the price point down to $400.
Agreed, I've been somewhat interested in VR since Oculus took off but I've sat back and waited for the price to drop, the Rift S at 399 is really really good, it was worth the price just for Project Cars 2 (which with a good logitech force feedback wheel is a joy to play).
