I really wish they focused on bigger displays too. For music/video production having at least 2x27'' screen size is crucial. But two is kind of weird because you can't centre any app. And there is kind of too much...
I've never understood why 2x27" is supposedly "crucial" for music/video production. I had two large monitors for a while; eventually I went back to one slightly larger monitor because I found it was more comfortable and ergonomic to be staring at a single surface perpendicular to my eyes.
Note that I mentioned "2x27'' screen size", not "2x27''". I would very much prefer if they just just glued two 27'' studio displays together, effectively making it a single 32:9 10K 49'' screen.
Personally, I want sharp displays with high pixel density. Multiple 5k / 27" displays offer that, a larger 4k or 5k display does not.
