I'm convinced though that a faster GPU will come simply to support the extra pixels I do think those extra pixels are a given.
However given a process shrink, pretty much a given, the reduced power draw and smaller feature size could easily result in a 50% clock rate increase. So even a dual core machine has the potential to be much faster.

It is really hard to say if Imaginations new GPU will make it in, Apple has been very aggressive with iOS devices in the past though. However some of Imaginations GPUs can be configured with even more cores than Apple is currently using. I could see A6 being a wash having to drive those extra Pixels.
Apple could put priority of those extra transistors on other tech to help lower power and increase performance.
They can do something like the iPhone 4 with the new iPad - higher resolution screen, Siri, 4x faster GPU but no noticeable improvement in performance due to more pixels being rendered. Then the 3S comes later with the fast GPU in 2013.
Except that iPhone 4S was a significant upgrade. I think we will see some performance increases because Apple is keenly aware of the various competitive threats out there. They will not want to rest least some respectable hard ware comes out.
It should be noted that various manufactures have successfully taped out 2GHz ARM cores for use in SoC.
Or, they can keep the same resolution, bump the GPU by 4-8x, add Siri, call it the 2S, sort out the screen glare using polarisation and have the iPad 3 in 2013 with a retina display and PowerVR 6 to drive it possibly along with a tweaked design and a convergence between iOS and Mac OS.
IPad 3 will be a little better than that. I suspect that iOS and MacOS will grow farther apart even as they cross pollinate.
More than anything though I'm hoping that IPad 3 has far more RAM. RAM more than anything limits the direction that iOS can go along with apps. RAM is an element that is often ignored when discussing future CPUs and GPUs.
