I was wondering if anyone had any thoughts on the chances we will see an updated 30 inch apple cinema display. Im debating picking up a few used ones on ebay but will hold out if people think apple might have a display in the pipeline.
Yes - it's called the Dell UltraSharp U3014. You can even have the generation after that with a 31.5" display sporting a 4K resolution, the Asus PQ321Q*, at least if it's worth $3500 to you.
* Does only work on the new Mac Pro in full resolution.
Go with the used ones whilst you can or an NEC Spectraview Reference 301. I think there is zero chance of Apple doing a new one. The failure rate on 30" panels is much higher than the 27". Thats why Eizo stopped selling them.
30Hz on a computer screen will strain your eyes, and I guess that the Mac drivers don't support the dual input mode as Asus makes no mention of Macs. Then again, they don't make any mention of anything on their product page.
However, the the worst case scenario is that you'll end up with two desktops next to each other.
