If you've been following the resort board at all, there has been a little discussion on this. Right now, several CMs have been saying that the current Winter Getaway rate is exactly the same as an AP rate would be. Now we all know that not all CMs are in the know, but this would imply that *IF* AP rates are going to come out, there are the same as they are for the Winter Getaway - which by the way, is just a code, not a package.
The other theory is that the Winter Getaway has to be booked by December 3rd and is valid for travel through February 13, so *IF* AP rates are going to come out for January or February, they probably will not come out before then. Current guess is a couple of days after that AP rates will be available *IF* Disney decides to make them available.
I'd book that Winter Getaway rate right now so you can get your airfare and then if AP rates come out, switch to them then,
