Dual 8K Resolution, I am assuming it wont be 60Hz, it will need to be 90 or 120hz.

I am not even sure top of the line PC can do that today. Even Dual 4K at consistent 120fps is pushing the limit.

At VR headset range with 8K Per eye is a display that is nearly 3000ppi. My guess is that 8K is the wrong figure and it is actually derived from 3000ppi. Which is similar to Varjo [1] HMD.

At lastly, this is "The Information". Which means it is an Apple leak. Intentional or Not. Over the years they have been doing PR pieces and other intentional leaks for Apple. It will mostly be the same tactic as someone else has mentioned, setting consumer pricing expectation.

They will use eye tracking and foveated rendering to reduce the hardware requirements.

Why will it need to be 90 or 120 Hz?

You need a high refresh rate to keep convincing your brain of the illusion. If you dip down to 60hz and below, VR sickness can be a real problem.

Motion Sickness. You can try it with FPS.

For me it is funny because the more realistic or better the graphics, a higher baseline frame rate is required. So my brain sort of work great with Counter Strike at 60 Fps, where the graphics are low Res and not any good by modern standard. Once it gets to very good / realistic level my brain sort of half interpret it as real thing. And expect "real" world motion. At this point 120fps feel so much better while 60fps cause me headache.

If we are not limited by computation constraint I would want to push for even higher frame rate rather than higher resolution.

60 hz in VR feels disorienting. I recently upgraded my video card to an RTX 3090, which allowed me to finally go from 90hz to 120hz using my Index. It was incredible how much the experience improved. I used to have a vive, and when I first got the Index the headset felt pretty similar. But once I improved the refresh rate it was a night and day difference in feel.
