well with the current displays at a price premium and LED backlit displays not as widely used (yet, they will be) there is going to be a bigger price premium give or take whatthe current displays go for.
just be expecting to pay the same price maybe alittle more fo rthat and unchanged ports for "updated" LED Backlit displays.

www.apple.com/displays/ gets updated @ apple.com (since its one of the last of the pages on the site to get updated and the information about the displays is using the "outdated" older information for the 1,1 & 2,1 MacPro video cards, so im guessing sometime this year they'll get rolled out ~ since the other products pages have been all updated to the current apple theme and look)
id still buy one now, im going to try by next week if a new one comes out, well see how well it fairs,i have no issue with purchasing one now and in the coming months trading it off towards one after i see how it is received
