It's all a fad with very limited real use potential.
WMR was never ever big enough to be a fad. It could never compete with the others.
Wow. That’s a huge blow to people who bought into WMR. Meta, valve, Pico, Pimax, and Beyond are all so much bigger now it must be impossible to compete for any return.
