The Oculus DK2 still makes me sick and the resolution is depressing, not to mention the awful screen door effect. Everyone keeps saying that will all be solved, but I need to actually be in a headset that doesn't trigger multiple discomforts before I can even think about developing for it. And the thoughts of it being a widespread consumer device are laughably premature. The hype is way over the top on what's being shown in VR now. Not only that, the current demos are mostly trash. They're either warmed over (usually FPS) demos of existing games that don't use the medium in any useful way, or they're over the top gimmicks that are meant to be impacting during a five minute expo demo rather than being practically usable.
Even if it does take off, it's entirely a game design problem. Production, whether it's the engineering side or the art side, won't change even slightly.
I'm sorry to hear your discomfort with the DK2, I personally love mine, and suffer very little ill effects after hours of use. as for your claims about the current offerings being trash, might i suggest trying Elite: Dangerous, Half-life 2, Dying Light, or with the help of software like vorpX, skyrim, gta V, and countless other games? for me the DK2 has been an eye opening experience, the effect of walking into another world is absolutely immense, and the sense of presence can be amazing. Don't put down VR just because it hasn't worked out all the kinks yet, what it does offer when you don't suffer from those symptoms is an overall amazing experience.
Do not get me wrong, the DK2 does have problems, but i do feel we are nearer now to actual VR games then we have ever been before. the Vive and CV1 models both look stellar, and although i am slightly disappointed in the expected resolution of the CV1, it does offer instead higher quality screens which should remove the screen door effect all together.
