Re: A few problems with these things
a) The Occulus Rift isn't on sale in its final form so I fail to see how we can know what it will cost at retail. Realistically it's going to be at least $300 but more likely $500. And Sony have never been known for selling kit cheaply.
b) Yeah and it costs a fortune. Look up "oculus rift recommended cheap graphics card" and they're talking of cards which set you back at least $300-500. Then you have the PC which goes around it. It's not cheap. In the context of this story, a PS4 is certainly more affordable, but what does it mean for the resolution, framerate and graphics it can push out? A low framerate exacerbates problems with lag so I would hope it delivers at least 720p60 per eye.
c) And it's still there and it'll always be there. It's caused by a combination of issues - lag, field of view, focus (or lack thereof), jitter, disorientation. Maybe they can minimize the issue but I doubt they will ever do away with it. Some kinds of games may be more amenable to the tech than others.
VR is certainly cool but when it comes with a massive price tag and known issues the question is how many people will bother with it. Look how many people bothered with 3D gaming (not many) and ask yourself why VR should be any more successful.
