I believe there will be AP discounts, however they are going to be very limited compared to previous years. Best gauge for where discounts would be to take a look hotels were there is a lot of availability of certain type of rooms. Typically AKL and GF see some of the most hefty AP rates.
Doing a quick inventory search for the end of September and beginning of October, there is still plenty of availability for a 4-6 night stay, this includes the time period of the recently expired summer promotion . So my gut feeling is that something is coming soon.
