Toshiba showed off a 498 ppi WQXGA 6″ display which of course makes a QXGA (2048 x 1536 or 2 x 1024 x 768) 9.7″ iPad more likely. This should make photography apps development interesting. Chances are the A6’s CPU won’t be much more powerful on single core* performance than the A5 or A4 and Apple doesn’t seem to like including much RAM in these things either. I expect to see a lot of apps that have trouble adapting to the new ridiculous resolution. The positive side: apps made by developers good enough to use the GPU or multiple CPU cores* will get the attention they deserve. But perhaps I’m being overly optimistic/pessimistic. The masses didn’t seem to care when most photography apps did 480×320.
* I expect the A6 to be quad core on iPad, but a dual core die shrink for iPhone.
