Having a DVC booking at BW in mid-July, I have been keeping an eye on this. Wanting something that approximates a "normal" stay, I am glad to see that, unless you have a DVC reservation, that you will have to pay rack rate for any available rooms. I cannot imagine 100% capacity allowing for much use of the amenities of the resort (pools, community hall, gym, etc.). If the parks are a gamble, you need to have things for people to do.
While I do feel for those who have cash reservations, you do have a choice and can get your money back. I have already paid a handsome sum for my membership, albeit 20 years ago, and annual dues. I will lose 70 banked points if I cancel. All told, this amounts to about $2500. I wish I were given such a choice.
