At least the displays Apple ships are very very good. Best in the industry.

I agree. I was the very happy owner of an Apple Cinema Display that served me well for many, many years, and was still in perfect working order when I had to abandon it in favor of an ASUS display because I needed more resolution and Apple wasn't selling standalone displays any more :-(

I want to be an Apple fan. I really do. But they are making it impossible for me nowadays.

Apple has mentioned that the next Mac Pro will also have a matching display.

I'm fine with a typical 4k display (or better). The panels of the better ones seem to come from LG anyway and are widely available on the market. I wonder if Apple would be selling a good quality 5k monitor with TB3, or if they go for a high-end 8k screen. Personally I'm not in the business for the highest end. LG has announced a bunch of TB3 screens, where the 4k 32" version would be sufficient for me. But LG lately has problems bringing their better screens in enough quantities to the market. Last years 32" 4k screen is still not widely available here in Germany.

I actually think that the 27" 5K display in the iMac Pro is going to age quicker than the internal components. I suspect that ~32" 8K displays will be mainstream in a year or two.

8K would require new HDMI cables and ports, would it not? I'm pretty sure that many people are still stuck with legacy hardware in this regard.

Current 8k displays use 2x DP connections just like early 4k displays.
