I don't think that this is purely a chicken and egg problem. A major part of total VR expense is GPU capacity; there is a certain level of computing performance that must be met for "good feeling" VR - but GPUs are and will be getting investment and improvements in price/performance even without VR; so the software/content folks can simply wait for the hardware to become more affordable, so that many more (most?) people would already have the required computing gear and would just need some peripherals.
