I've read an opinion piece that theorized that HTC is catering to businesses (mainly VR-gaming cafes), so not quite enthusiasts, but the same idea of higher price lower volume. The evidence being that stuff like the Vive Pro and wireless headset are really expensive, but the purchase makes sense if you're making money off them. I can't recall the source.

Another piece of evidence would be that "Enterprise" is featured prominently on the Vive website.
