While I am not so shocked about the price (good, high-end monitors start at 500$ ... I wouldn't play a goodlooking game on a crappy TN screen no matter how low the lag and how high the refreshrate. Good, high-end TVs start at about 2000$. Why should a good, high-end VR Goggle cost any less than 600$?), I am not so convinced that VR is already going to take off in 2016... or that I actually want to expierience that, yet.
600$ certainly is not too expensive. It replaces your screen, or at least it could do that in the future. Any new screen I would get at this point would be 4k, HDR, at least IPS, better VA, even better OLED technology, more than 60Hz refresh rate if possible, and/or variable refresh rate (preferably not the vendor locked Nvidia system)... there is no point in getting any cheaper compromise Screen just to enjoy a fraction of what gaming of the future should look like that I will likely throw away again in 2 years time. I am not so fussed about 120 Hz gaming or a variable refresh rate that I would step down to a TN screen.
So I will spend upwards of 500$ likely on my next screen, as it should be a high-end, no compromise model.
What I am questioning though is if there is a killer application coming in 2016... or 2017 for that matter. It's not enough to make VR a gimmick tacked unto a traditional expierience, like many 3D movies did with the 3D expierience.
And without many other advancements, VR will be severly limited in what you can achieve. I could see myself grab for my wallet for a more immersive "piloting expierience" in flight sim games, or space games... the tech certainly is there for such things (just don't forget to include better control options than fking mouse&keyboard!)...
Anything that requires your character moving around without the frictionless "threadmill" tech that showed up on Kickstarter some years ago? Na, too much compromise... not going to bother. Seen to many early-early-adopter expieriences that gave you a glimpse of the future for extremly inflated prices and ended up disappointing in the end.
So Rift or Vive.... as long as the Software isn't there yet, and the rest of the tech needed for true VR doesn't catch up, I will only bother if I find a simulator game that I want to spend 600$ on to make it more immersive.
