Kinda crazy that more people aren't excited about this.
The MiniLED displays on the MacBook Pros are AMAZING.
Extremely good contrast, not OLED, but 25,000:1 is still an incredible experience for watching movies in a dark room.
This will no doubt be 5K120HZ, so it will have ProMotion and it will have Retina PPI for productivity.
It will also be much brighter than the Studio Display, which is already quite bright.
The only thing they need to fix besides this is the terrible webcam quality, and ideally upgrade the speakers further (Studio Display was good, but not as good as HomePods).
Also, this monitor almost certainly will offer 5K120HZ over ThunderBolt 4, so I wouldn't worry about needing ThunderBolt 5 to get the full functionality.
You can do 5K120HZ over TB4 with DSC, which Apple already utilizes in the Studio Display and Pro Display XDR.
I just struggle to get confident with their Mac accessories nowadays, you're far more confident than I am.
I'm anticipating a refresh with mini-LED, still with standard 60FPS and probably newer Thunderbolt ports and that's basically it, Apple have honestly been a bit disappointing with their display offerings and I can't see them going all in and adding everything that would make it a great display considering the Studio Display was a weak option when they started offering that.
The Pro Display XDR was fine when it was the only one in its niche but now competitors are offering relatively similar displays with generally just worst with overall peak HDR brightness for a fraction of the price.
I am looking at setting up a dedicated graphics workstation in my home office and I can't even consider the Apple displays in good conscience when the new LG 6K 32U990A is on the horizon and has pretty much just cloned Apple's design language, if it has a glossy option and half the price of the Pro Display XDR as is expected then it will be a must-buy monitor in the Apple world.
