Which is why it was important for them to focus on the 8k. Sure a better 4k model would be great & they should even release a new version with the screens & dp with native 4k and change of lens focus & hardware mild ipd adjustment to improve sweet spot for wide n narrow ipd comfort.
To truly break into the VR world they needed something to set them apart. 4k was a good start to get noticed; butbiw wouldn't suprise me if LG delays to release there steam hmd with 4k as Samsung has for purposes is releasing a 3k ish headset.
Now an interesting idea for the PiMax team would be to release a new kind of 4k headset or sorts.
2x. 2048x1600 screens with a FoV of say 160° with an upscaler option built based on 5k & 8k modular design.
