17" Might Get A 2.6GHz Option Offered
I agree on the 15". But, like you, I'm thinking the 17" may get a 2.6GHz option added in October-November time frame. LED I don't know. But 2.6GHz seems like a doable addition ONLY to the 17" as it can run cooler due to more space.There is nothing to refresh with pre-Penryn. Maybe the 17 incher goes LED and gets the Merom Extreme for mega-ultra bucks, but there's little to do for the 15 inchers.
No MBP pre-MWSF (and even then, maybe nothing until Feb/March).
