Take a read and also talks of 8k as well.

If we wait long enough: Yes!
However, I see no need for 8K on a tv - for bigger screens/public viewing it might become relevant.

....got sick of it.
P.S. They say it will boost a 'certain' online industry...
....so maybe I should try again.

When I tried it in a Samsung store (not a 'certain' online industry) I was surprised how terrible the image was. I said it was VGA quality. But it was 2K. However when the screen is stuck on the end of your nose (trunk in my case) 2K does not make the grade hence why I think 8K has a future.

Trunk, heh.
As for sick, I worked in the early 90s in a university research lab on simulation and such, and we had a VR group. Back then it was tough as it was hard to get graphics cards and computers to be fast enough to work on VR, and we had to use very expensive Silicon Graphics image generators. Even then it was tough, as little issues like lag and inaccuracies in the head tracker would induce "hug the trash can" levels of simulator sickness, a kind of motion sickness brought on by the VR environments or even simulators in general. If you move your head x deg and the image moves y deg, if y is very close to x, not much problems, if it's way off, not much problems either, but if it's not nearly perfect but a little bit off you can get huge problems. Lag will also cause issues, to the point that when they ran student volunteers thru tests with the VR headset they'd drop the temperature of the room down to about 60 deg F and put a trash can with a plastic bag liner in it right next to the chair the test subjects sat in.
One job I had the director of the office was so prone to simulator sickness he could only sit in front of a monitor, no headsets, and play with the product, an immersive infantry simulation, for about 2 or 3 min before he started to turn green and had to get up and move around. Funny liability for a man who ran a simulator company.
There are other issues too, one of which was that after spending time in the VR headset you were supposed to wait at least half an hour or more before driving. The issue was that in the helmet your eyes were focused at infinity, and you got depth cues only from angles and such, whereas in the real world your eyes also use focus (difference in eye focus for near and far) in addition to moving your head and seeing how things change to determine depth, you lose the eye focus info in the helmet. When you come out to the real world, it takes a while for your brain to switch back to processing things differently, and your depth perception is off for a while, not a good thing for driving.
We always thought these issues, plus the fact that the modelers who spent a lot of time in the VR helmets had their vision deteriorate, got a lot more nearsighted, kept VR from moving into the gamer world as they didn't want liability from both accidents and screwing up kids vision. I guess we will see how that all works out now as everyone seems to be moving full speed ahead on this.

I'm afraid I'm recovering from the BeoVirus.

MM, You are probably correct. There is no need for 8K, However 16 hours of the 2016 Olympics will be broadcast by NHK in Japan. The 2020 Olympics will all be broadcast in 8K. 8K TVs are available now but at a high cost. At least 3 companies are working on 8K TV and 8K cameras are already in use. 8K is inevitable
It would be nice if they'd let one massive technology upgrade come to fruition and either succeed or fail in the marketplace before hawking another (4k vs 8k). At least they waited until 3D was dead before pushing 4k.
I've seen 4k demos, and while when viewed very close up there's an obvious advantage, at "normal" seating distances from the display, meh. Even the Imaging Sciences Foundation, who have long pushed for better displays, rate resolution fairly low down on the list, black levels/contrast, gray scale linearity, and color temperature/accuracy rate higher for creating a realistic display.
The part of the standard for 4k that actually has a chance of improving TV viewing is HDR, if it's implemented well and the displays can actually produce that wide a gamut of light levels. My 1080p Panasonic VT plasma still looks better to me than any LCD I've seen, including B&O. Hard to compare to OLED as ever OLED set I've seen is seriously misadjusted to eyeball searing brightness levels. The THX setting on my Panasonic is as close to properly setup as any TV out of the factory has ever been, with the possible exception of my old Proton tube set that I got ISF calibrated from the factory as an option.

I guess I was somewhat wrong on this issue. NHK will start broadcasting in 4K and 8K in 2018. Is there a 16K?

Hello
I can confirm that some of the Olympic Games in Tokyo will be broadcasted in 8K.
CIO/IOC is one of my client in Lausanne, Switzerland.
Their digital storage is 4K ready for Rio, but they are already planning to have 8k compatibility for the next summer olympics in 4 years.

It shall be regarded as more of a testrun för 8K.
