i see graphics being updated to 9400 on the low end and maybe something like the 9600 in the macbook pro on the high end, just like Macbook getting ready for Snow Leopard. I see processors upgraded to whatever fits on the Intel roadmap as that's what Intel likes to sell and Apple is way behind. Remember, Apple doesn't use "desktop" processors in any devices, only laptop or server processors so they get a better deal buying in volume but you won't see quad cores because those aren't for laptops. I don't see an new format coming out so soon after changes to the "aluminum & black" format that the iMac started a year ago, but maybe another matching display. And of course, there won't be no new mini... but we can hope!!!
