A few thoughts...
I currently have a 24" ACD and I would like to upgrade, but because of the above, I'm trying to hold off.
- I think a nice upgrade would be for Apple to use anti-reflective glass
- From my understanding the point of Retina is to not have visible pixels - I can't see them changing the resolution much. It would be hard for them to manufactor the panels
- I could see OLED panel being used - which would greatly decrease the thickness of the ACD
