For those of you wondering....before October = August or September
"At the time, Kuo believed that Apple could have the 13-inch version ready by August, but in the wake of WWDC he revised his predictions to indicate that Apple would begin ramping production in September for a launch in October."
If they're aiming for the before school crowd, they're going to miss it by a couple of months...
I've no doubt they'll update to the Retina, of course. But at this rate, Apple is announcing the iPhone 5, iTV, the Mini, and the 13" MB Pro w/ Retina display by October. Oh, and the iMac lineup, too.
I love rumors. Apple did say they expect an "exciting" September, right?
