Will discounts be offered for a sold out resort?

I have a room only reservation for September at Wilderness Lodge. I was hoping to add a room only discount when they came out. I have never had trouble doing this in the past. However, I just checked and the whole resort looks to be booked for my dates. I am assuming this is because they used half of the rooms for new DVC rooms. My question is has anyone been able to add a discount when all rooms were full? Will WDW even offer a September discount for WL if there are no rooms available?

Nope. Not likely. This is why POFQ is pretty much never included.
