Are there any information of what models will be offered yet? I know Apple website shows the "Up-to" values, with 12 cores and stuff. First of all I am assuming that is not a physical 12 core processor. It is either 2 6 core processors, or just one 6 core processor and they are trying to sell hyper threading as cores. Second, not all of us can afford that thing with 64 gigs of ram, dual gpu's and stuff. I wonder what will come base equipment and what it can be upgraded to. I think it said dual AMD GPU's is standard, which is a shame since they are automatically alienating anyone who uses MATLAB and wants to do Cuda core computing on a Mac.
