I love that you've not only checked it 4 times, but are able to give references to the times in which you've checked it.
I need say no more.
It will be the base spec with the GTS, Airport and Bluetooth. Then I'll stick 8gb into it after that.
Dilemma at the moment is that if I wait until next January (or the next revision) I can get the highest end model they do. Something similar to the spec you got, with the CPUs. It's so far away though.
Not content with 8 cores, but wanting them to be 3.2ghz too. I hate the greed Apple stirs in me.
