probably oculus will jump on it, easy way to fill the gap with pimax, and after all they are already hand to hand with samsung...(something like your hardware/our software)
Pimax being chinese and samsung korean, i do not see a match here.
Chinese would likely wait to get the product locally for cheaper.

The rift has a native resolution of 2160x1200 (or 1080x1200x2, both have the same pixel count).
Pixel density isn't a direct multiple of this. 1.0 doesn't mean 2160x1200 and 2.0 doesn't mean 4320x2400.
Pixel density is the desired ratio of texels to pixels in the centre of each eye after the post processing distortion phase. Due to the barrel distortion done in the distortion phase, you need to have a higher resolution (centre pixels are bulged larger than outer pixels).
To achieve 1:1 ratio of rendered texels to panel pixels (this is pixel density 1.0), you need to render at 1.23 times the native res. (DK2 lenses needed 1.5 times, DK1 was around 1.7 I think)
So setting the density to 1.0 means your game is really rendering at 2664x1586 (the panel is of course still 2160x1200).
Pixel density 2.0 means two full texels (per axis) per panel pixel in the centre of your eye, which means the game is rendering at 5328x3172. Get out your calculator and you'll see that 5328x3172 is 16,900,416.
So when it comes to performance, the Pimax 8K X sounds like it will require extreme hardware. But anybody who can run a rift game at density 2.0 is already doing a bigger GPU hit.
Potential vertex pipeline hit due to wide fov, however, is a discussion for another time (I'm at work).

Im really interested to see how these new headsets turn out. I'm sure Oculus won't leave it too long until they announce a successor.
Again, about the 8k x resolution... I read that rendering at 2x pixel density is roughly the same as the Pimax. However, i feel that even a 1080ti cannot reach this at 90 for most current more graphically intense games. Actually quite far off. Also we need to consider, that future games over the next couple of years will be even more gpu intensive. Negating somewhat, the boost new gpus will give. A gpu in 1yr that is 40% quicker isnt going to run the games released in 1yr at 40% fps boost.
