I hope apple doesn't get behind with its MBP 13 since the hp envy 13 has at least icore 3. the least thing apple can do is to put icore 3 to its mbp 13 otherwise, the 13 won't be the most purchase laptop from the company anymore
My understanding (and I could be wrong) is that with the 13" Envy you either have an SSD or the optical drive is removed, and this is how you're able to get Arrandale plus dedicated graphics. Because Arrandale is a two-die solution, Apple would have to make some room on its 13" logic board to be able to offer dedicated graphics. I think it's unlikely Apple would make the optical drive optional but we'll see. Otherwise users may be stuck with Intel's integrated graphics, and that will disappoint many people. Of course the other option is no Arrandale but just a C2D spec bump on the 13", and that would disappoint many people too.
