Sharp Announces 2nd Gen 8K UHD TVs at IFA
Sharp this week introduced its second-generation 8K ultra-high def TVs at IFA in Berlin. The new televisions use the company's new panels as well as the latest processors that can upscale Full-HD and Ultra-HD 4K content to a 7680×4320 resolution.
The initial lineup of Sharp's 2nd Gen Aquos 8K UHD TVs will include models featuring sizes of 60, 70, and 80 inches. The new televisions will be based on the company's new image processor that doubles its compute throughput over the predecessor and can upscale 2K as well as 4K content to an 8K resolution with a 100/120 Hz refresh rate.
Samsung's first 8K TV goes on sale next month
Samsung is announcing its first commercial 8K TV, the Q900R, at IFA 2018 this week. The QLED panel will be available in 65-inch, 75-inch, 82-inch, and 85-inch sizes, and is capable of peak brightness of 4,000 nits. It also supports the newer HDR10+ format backed by Samsung and Amazon.
The incredibly poor detail of 4K makes my eyes bleed; it's impossible to look at. At least now we'll have some more 8K options to tide us over until we reach 64K (61440×34560).

Lenovo Mirage Solo is 2560×1440, 75 Hz. Oculus Go is 2560×1440, 60-72 Hz. These are "standalone" headsets, which should be considered the baseline since they need to operate using battery power. Other headsets can use a fast, short-range wireless connection and visually lossless compression (5:1 may be possible) in order to deliver graphics from a gaming PC to the headset.
Horizontal field of view is about 100° in these and some other headsets. This should be doubled to about 200-220° to encompass the entirety of human peripheral vision. That also means a doubling of pixels.
Some headsets are already busting way past 1080p. The Pimax 8K (misleading name?) is 3840×2160 per eye, for a total of 7680×2160 pixels.
Ultimately, we want the frame rate to go up. At least 120 Hz, maybe even 240 Hz [reddit.com].
Incidentally, Pimax came up with a technique they call "Brainwarp" that displays 1 image to one eye at a time, and alternates. So instead of displaying 7680×2160 at 120 Hz, they effectively display 3840×2160 at 120 Hz, and you perceive it as 7680×2160 at 120 Hz. Half the GPU power is needed, and they dual GTX 1070s or a single GTX 1080 for this. That's a far cry from the 4-way SLI you're talking about.
Most GPUs aren't at "10nm" right now. Nvidia's GeForce 20 series is at "12nm". "7nm" will be coming soon. While it's possible that we could go below "3nm" [semiengineering.com], you were probably right to pick that as a stopping point. However, if we ever make "3D chips", we could reach far greater performance with a reprieve from the death of Moore's law.
There are many tricks that can make ultra high resolution VR and high frame rates possible. The most obvious is foveated rendering [theverge.com]. By tracking the user's eyes, you don't need to render the entire screen at the full resolution. This is explicitly mentioned [roadtovr.com] in research related to LG and Google's 1443 PPI display for VR. Google's Seurat [soylentnews.org] is another thing that can reduce the burden. Add up all of the little tricks, and suddenly realistic VR is not so hard anymore.

None of AMD's GPUs are using Infinity Fabric + multiple dies yet:
