The market for a high end HMD is pretty much anyone that already has no problem spending $1,000 on a video card. That is a lot of us but it isn't big enough for a company like Facebook or HTC. My fear is pushing crap at $500 instead of gold at $900 will leave a stigma on VR that will take another decade or more to wash off.
The reverb actually looks great but the tracking is a flop.
