Possible in a Quad, if Intel lowers the quantity pricing (i.e. speed bump but the same or less than the current W3520 used in the base).I'll be kinda bummed if all they do is add a top of the line BTO option. I'd at least like a speed bump on the $2500 price point...
It may be technically possible (current base E5520's are cheaper than the E5462's used in '08's base Octad), but Apple's wants higher margins than that price would provide. The pricing on the next chips won't be cheaper either, as there's at least a die shrink that needs to be paid for (R&D + facility upgrades).I'd be happy if the $2500 machine got me an 8 core dual. Certainly a better deal than the current 09 machine...
So it's not going to happen.
