This is what makes sense to me. I doubt the game will run at 2880x1800, but more at 1440x900 with Retina support.
That doesn't make any sense at all. Are you saying the screen UI overlays (the stat bars and such) would be 2880x1800, but the other gameplay elements would be 1440x900? That shows a complete lack of understanding about what a resolution is and how 3D games work. If your screen display resolution is set to native (2880x1800 in this case), then that's the display resolution, period. A 3D game isn't going to pixel double every pixel in the 3d environment portion of the game...The game engine will output to the target resolution. If the MBP is put in charge of the pixel doubling, then it will pixel-double all screen elements, including the IU, and the effect will be exactly the same as looking at a 2011 MBP screen with it's native 1440x900 resolution, excepting some small fuzziness induced by the pixel doubling (as long as the scaling remains 2x or 4x or a multiple of 4, the pixels won't get super-blurry due to interpolation).
If that's what they were talking about, then it's not Retina-enabled at all.
The only possible interpretation of that marketing point from the presentation is that D3 will run at full 2880x1800 resolution. You can completely disable AA for any game running on that screen due to the super-tiny pixels, which will free up a lot of graphics power to do other things like shadows and pixel shaders, so it probably won't be the huge performance hit that many are worried about.
Frankly, this first generation of "retina" laptops are not the ones you want to buy...Too many new things going on here. Next year they will be much more capable of pushing all of those pixels.

What's wrong with 80 degrees C?
Can't speak for that guy, but on my 2011 MBP, that's about where the overdrive fans kick on and you have to yell to have a conversation with someone else in the same room.

Good news so far.
If this thing can do 20 fps on 2880 x 1800 it will probrably run on 1920 x 1080 decently ( which is amazing)
You wouldn't want to do that, though, because it's not 1/2 or 1/4 resolution, so the pixels would have to interpolate and get all fuzzy.
It would, on this screen, look significantly better if you played the game at 1440x900 with AA turned on than it would if you played at 1920x1080, with or without AA.
