I'm not sure about novelty-only, I believe it has very interesting use cases, but I sort of agree on it not being "explosive technology".

To really make an impact in daily life it has to become usable in public, and the chances of the tech industry getting the tech, the applications and the dorkyness-factor of HMDs solved are pretty slim.

I only see it used in professional contexts for quite some time (e.g. Lockheeds and GEs ideas for airplane maintenance workers seem sensible to me even with relatively high cost attached, if it gets really cheap I could see warehouse workers, building maintenance, ...)
