So I know what your thinking "there's no room" "it can't fit" well, let me ask you something. What are we waiting for ? Retina ? No, and I'm 100% sure apple are not stupid enough to put a mobile GPU with retina, unless it's a really really good one like for example this years version of the AMD 6990m, and if they don't you won't be able to do any graphic intensive stuff, which will be a real buzz kill. And the "new" iPad got a nice fresh retina screen, and guess what ? They upgraded the GPU to support it, so it only makes sense to do this with the iMac, and if it does in fact have retina, I have a feeling we iMac lovers are all in for something big this year. And so it's not today so perhaps WWDC ??? Post your thoughts below.
