The Retina Display is said to be 326 dots per inch at 960x640 pixels.
The Apple Cinema 30-inch is around 100 pixels per inch at 2560x1600 pixels. For it to be Retina Display resolution it would have to be over 3x as dense over a hugely larger area...thousands of pixels wide and tall. You can't even buy anything like that today. If you could it would be hideously expensive. The thing is, it's easy for Apple to build a 326 dpi display if it only has to be a hand-sized 960x640. Building one 30 inches diagonal would be an extreme manufacturing challenge at this time.
Make that 2030. And only if Steve is still running the show.
About 10 years ago a division of IBM made a very interesting display far ahead of its time. It was code named Big Bertha, was a 22.5" diagonal LCD having a resolution of QWUXGA (3840 x 2400) which worked out to just about 200 pixels per inch. It sold for around $30,000 and found only a limited market. It had about a four year production run and closed out at around one-fourth that original price. It required four independent DVI connections in order to drive it.
It used a copper-on-glass metalization process that was developed uniquely for the application as normal ITO would not suffice for the conduction layer owing to the small pixel geometry. I'm not sure even that process would scale to 30" and 330 ppi. Anyway, don't hold your breath waiting for this display.
