It's a chicken and egg problem. VR tech isn't taking off cause there isn't enough market share to justify having great games for it.
To get that level of market share a company basically needs to subsidize the initial hardware/consoles. I don't think Valve has ever learned that concept and as such they are still selling the hardware at full price. This in contrast to say FB/Microsoft/Sony who actively subsidize their offerings because they understand the benefit of getting people locked in their ecosystem.
I predict a repeat of Steam Machines. (as a Linux user)
