Perhaps although you do realise that apple was behind with its resolution on the iphone 3gs when it quadrupled it with the iphone 4 ? 960 × 640 is high, but not that high taking into account the 640*480 my acer n310 had in 2005/6 .
Now manufacturers are anouncing/releasing 720p screen of that size , yet that means still 3.5 times less then what you would need when wanting a 2047* 1536 , and that in a couple of months? Massive production readY? I dont think so.
I think they are going to improve the way ipad/iphone handles lower res apps and perhaps a 1.5 times higher resolution, but I dont see them introducing 2xxx resolutions early next year.
