I've boiled down to this simple guess: the printer promotion. At the moment you buy a printer anytime before 19 October you can get a rebate. There's no coincidence that Apple releases new products when rebates expire but the date certainly coincides with "a few weeks", as well as being two days before the release of Windoze 7.
And what would it include? I guess bluray and a new design (hopefully), along with a significant spec bump because it'll be a long haul until they release the next update.
I hope I'm right lol. And I hope some Apple employee reading this won't delay the launch date by one day so they can say I'm wrong
heeheehee... Well, if the computers do come out earlier than my guess then I can get another printer for free
