I can't see them adding much if anything to an existing offer. Typically they offer the dates and resorts that they want more resort bookings for. If they are not offering that week, they probably have already have enough bookings to make them happy.
The same with the first week in December - apparently a lot of people booked this year based on past offers and the fact it is typically a slow week, and now the week is pretty well booked and there are no offers for free dining.
It could change, but I wouldn't count on it.
