Well the Dell 5K monitor we've seen demoed should be available around the holiday season (~$2500???) so its not surprising that Apple would or could be using some of the same or similar panels in their products as well. The problem for Apple on the iMac though would be how they would manage to attain the 5K resolution support internally on what is essentially laptop level video subsystems when Dell used a Quadro K5000 and dual Displayport 1.2 connections for their demo.



Naturally one would think that this is going to be an expensive option for the iMac so the 2560x1440 option will still be offered.



It doesn't make sense to skip 4K though because that could be managed a little easier and cost a little less while still being a healthy upgrade from their standard 2560x1440 models. So maybe three screen resolution options,....but then Apple isn't known for giving a lot of choice or options,....
