I have modest predictions for this round:
Same form factor and price.
Antiglare coating.
Ivy Bridge and USB 3.0
Up to 1GB 7750M in the 21" model, 2GB 7970M in the top 27" model.
Possible change from the SATA-II Toshibas to the SATA-III Samsung 830 as the BTO SSD.
(Frankly, as long as the 21" gets USB 3.0 and a 1GB 6950M or better, I'm sold.)
I pretty much agree with what you have said. I will be buying the 27". I just wish this would come out in time for Diablo 3 (May 15th). So what's a realistic date? Early June since there is no official release date for the 7970m.. :/
