I don’t think VR is a fad. It’s a new technology, with a ton of new hardware and new hardware specifications. It’s going to take some time for the cost of those parts and manufacturing to be reduced in cost. 2nd gen will be 3/4 the price of CV1, CV3 will be 1/2 the cost, etc… Just like any other technology that has come prior.
TV’s aren’t a fad, are they? Well, sure, I guess they are. But they’re a long term fad 
Same with cell phones, smart phones, tablets, computers, cars, planes, etc…
