As long as Apple Studio Display 2 offers a glossy coating again, Apple has already done a lot right.
The following attributes should also be implemented:
1. 6k resolution with 218 PPI, ergo = 31.5"
2. 120Hz+ (with Thunderbolt 5, Hertz should technically be able to exceed 120)
3. More connections than just Thunderbolt 5, i.e., also DisplayPort 2.1 and HDMI 2.1
4. Speakers
5. A webcam that could support both Face ID and Windows Hello.
6. Price not exceeding US$ 2,200
7. And again, for the sake of completeness -> GLOSSY!!!!
