Re: Let's face it--true VR is a Unicorn.
I'm not sure anyone was expecting "true" VR, but VR is already the best option for flight simulator users - quite a large demographic - and it will only get better.
The main issues are resolution and field of view, which PiMax seems to have made great strides with, and comfort. Just a well designed headset strap is enough to make a large difference to the latter issue, but a little less weight on the front will be possible with newer technology.
