It probably wont. Due to some licensing restrictions, apple was forced to put crappy intel graphics into the latest MBP, because intel isn't allowing any other manufacturer create iX sockets on their motherboards... At least they aren't letting them be used, not sure exactly what the wording is. The point is, if apple included the iX processors on a computer that doesn't have enough room for discrete graphics, then it'll have to be integrated graphics, which means they'll have to use intel graphics as the sole GPU, to replace the current offer of the Nvidia GeForce 9400m GPU on the 21.5 inch models. That would blow so hard... Say goodbye to performance... There's a games don't support intel graphics usually, they just plain suck.
