Those looking for a new Apple 30" might want to consider this new one:
Dell U3011:
The screen is a 16:10 format display which will use a 10-bit H-IPS panel from LG.Display. This will be the LM300WQ5 panel which is listed on LG.Displays website at the moment. A version of this panel is already being used in the 3008WFP although with an 8-bit colour depth. Looks like they have perhaps done the same as they did with the 24 panel used in the Dell U2410 and HP LP2475W. This came in an 8-bit (used in the HP) and a 10-bit (used in the Dell) version, with the same part number, just a different revision. Given the newer spec here from the U3011 and 10-bit colour depth (8-bit +AFRC), I expect the same is true here. An updated panel revision for use in the new model.
This model is designed to replace the 3008WFP and so has some improvements in the spec as you might expect. This includes a 100,000:1 dynamic contrast ratio, 7ms G2G response time and 12-bit internal processing. There's a whole load of interfaces available including 2x DVI, 2x HDMI and DisplayPort.

The screen is pencilled in for a release date at the end of October at the moment, but could possibly move a little sooner.
