For 2010 AP rates are available through June 3rd. They are quite steep, especially if you are staying 4 or more nights. I'm not sure when they will be released for the remainder of the year. Hopefully around March/April.
The AP rates are great. I changed our Poly reservation to a Club Level-Lagoon view for about $100 more than I was paying for a Garden View at the Disney Visa special rate. If you plan on arriving before June 3, it is worth checking it out.
Also, if you receive a pin, it can be for a trip 8 months out. We received an AP pin in October that was good through June 10. Bounceback offers can be up to 12 months in advance as well I believe.
