Yeah, very much looking forward to headsets with 8k panels. Most are up to 4k now, and it's getting pretty good. If it stays at 4k for a bit, that would be fine. But it's definitely an area where 8k will still be a very noticeable upgrade.

Even if the only short-term practical use for an 8k panel is how far away a 4k or 1080p screen would be clear to read in an augmented reality situation, that would be reason enough. But I personally will gladly lower quality settings to run VR games in 8k instead of 4k as well.
