So you admit their decision has nothing to do with [...] any logical aspect relating to technology or capability.
I think the OR guys have realised that the first iteration of the OR will only just be hitting the minimum acceptable quality. Even 1920x1080 isn't ideal, and they'll want to move to 4k as soon as possible, and have said that the experience will continue to get better until 12k has been reached. Also, 60fps is the minimum acceptable, and they want to increase that as much as possible too.
As new screens come out, with better resolution, better colour-switching times, and all the rest of it, then they will release new iterations of the hardware. PS4 could no doubt handle the earliest iteration for a lot of titles, and probably even provide 4k experiences on games that aren't too graphically complex, but won't keep up with the pace of PCs. Judging by various Battlefield 4 benchmarks, my rig is roughly on a par with a PS4 already, so when I switch graphics cards in two or three years, I'll be well ahead again (even taking PS4 software improvements into account).
It's still early days for VR, and things are changing quickly. The Oculus Rift hardware is tied into the mobile hardware market, so as a comparison, we can see
what smartphones looked like when PS3 was released, compared to
what they look like when PS4 is released. The rate of change in that sector is quite phenomenal. If it continues, I imagine we'll be seeing much better versions of the Rift coming every couple of years or so, which is a problem for the consoles.
