Okay, but if so that won't be releasing on PS4 unless Sony are flat-out liars. Either the final product will be optimised, or it'll be canned as a PS4 title. What we're really looking at here isn't PS4 being no good for VR, but the possibility of Neo-only PSVR titles. Titles experienced on PS4 and already proven high quality like Rigs proves people won't be calling PSVR a dead end on PS4 - get Neo.
That's not at all what I've been seeing. No-one's called PSVR glitchy, slow or horrible. There have been complaints about some games, and some control schemes perhaps, but the experience works and provides immersion.
