I worry about the performance hit those screens might give to AAA games, though. Even a high-end card would have trouble pushing those pixel numbers. The mid-range cards they put in iMacs will surely choke. And I'm one of those people who refuses to run games at resolutions lower than my screen's native res. So lowering the resolution into fuzzy territory is out of the question. Do iMacs really need that many pixels, anyway?
I'm one of the people as well, where running on native resolution is the most important graphics setting to me. However... this will not be an issue on the Retina displays.
If they retina the 15" MBP in the same way they did the iPhone and iPad, they're going to up the resolution from 1440x900 to 2880x1800. That's clearly a ridiculous resolution for gaming. Anything other then top end desktop GPU's with the power of a GTX 670/7950 and up could run that, however you don't need to run the games at that resolution at all.
Due to the awesomeness of Retina'ing a display. Running an image at the old resolution, looks the same as it did running it natively on the old tech. Running a game on your Retina Display MBP at 1440x900 resolution, will look identical to running a game currently on 1440x900 native on the present MBP's. They can simply have 4 pixels act as one pixel. The 4 pixels take up the exact same amount of size, and as such, your eye's will not be able to distinguish a difference between the 2011 MBP 15" 1440x900 screen, and the 2012 MBP 15" screen running at 1440x900. Now if you use any resolution other then 1440x900 you'll get that horrible grainy, distorted effect that your used to when you use anything other then a native resolution.
Example:
Now I expect your eyes are going to get used to 2880x1800 detail, so you'll want to run games at that res, but running at 1440x900 will look as crisp and native as it always did. Apple is pushing the industry forward to higher PPI screens

and that is a very good thing.
