I'd be a bit nervous if I were hoping for an October discount.
I went on Disney's site and played around with a bunch of different reservation dates at different resorts (mind you, these were just standard reservations, not discounted "special offers").
October is really booked (particularly late October, where resort choices are slim pickings). Early November is also pretty booked (although not as much as late October).
Interestingly, the closer one gets to the middle of F&W and the lead up to Halloween, the more booked the resorts appear to be.
I'm starting to wonder whether part of the reason Disney seems to be dragging their feet on fall room discounts is that they don't intend to offer much (if anything) for October. Plus, I'm guessing they're waiting to see how the combination of FLE + FD plays out. So why rush?
