I'm searching for a MBP around the 13'' (or smaller) range w/ an dedicated GPU. Like most others, I'm anticipating the release of Diablo III. I'm currently on the latest gen Macbook Air 11'', and although it "technically" runs on lowest settings, I have no doubt that I'll be experiencing much lag and fans at warp speed. And of course, there's the practicality issue of gaming on an 11'' screen. However, I was surprised to see that Apple does not produce 13'' models with dedicated GPU's... I remember my old 13'' MBP (from 2010?) had some Nvidia card that was able to run L4D/Starcraft II just fine (albeit some lag). I have no doubt that the current 13'' MBPro's with the Intel HD-3000 cards (or whatever they are) wont be able to perform even with the upgraded CPU's. My question is this: Will Apple be installing better GPUs into the next 13'' models? If so, will they be decent enough to run DIII and other Steam games (LFD, etc)? Or did they phase them out for 13'' completely so that only the 15''-17'' will be the only ones with them? Portability is a very important feature for me, and I really don't see myself lugging a 15'' around. (I know it's just two more inches from the 13'', but I've gotten more than used to my 11'' kitten...) The desks at my lecture hall barely handled my old 13'' MBP that I had... 15'' would be disastrous. Thoughts?
