Hello world. I have been following this thread for a few weeks now and finally just registered. There are a few things I wanted to say/ask --
When has Apple EVER refreshed a laptop lineup twice in the same year? That seems abnormal to me, but I could be wrong.
I believe when Apple referred to discussing details in October they meant for analysts to interpret that as when the next earnings call is, since they can then go over what has been announced in the months between now and then. The statement was in the context of why they cannot discuss the details on this particular conference call (but can on the next). If Apple plans on a release prior to the conference call, I think it is plausible for a September announcement and maybe October shipping dates for the rMBP updates.
That being said, if we're expecting a September event for iPhones and such, I think it would be very Apple-like to cover all of these releases in a single event rather than doing an entire other presentation and getting the entire media together again only weeks later. This scares me because I have a distant memory of Apple once saying "shipping for the holidays!" is a past release, but maybe I am remembering incorrectly.
I'm dying for a 13" rMBP 512gb with some more power/juice, but am going to be patient and wait for what everybody expects will happen soon. I just am concerned our expectations may be high despite the "busy fall" talk we hear since we therefore must be expecting "early 2013" laptops and "late 2013" laptops. I (and plenty others) don't want to wait all the way to September just to get told "holidays" or "by Spring!", you know?
There will definitely be a lot of announcements this fall, but I find it hard to see a 2013 refresh followed by a 2013 refresh, you know?
EDIT: I also wanted to add that I of course recognize the numerous price drops on current inventory and how it would be seemingly absurd to have Airs outperform some aspects of the Pros for an extended period of time. I don't discount Sept/Oct release possibilities for reasons like this, but the pattern just seems very atypical of Apple.
