For me the 2042 expiration for many resorts is the elephant in the room.
Whatever they do, they have to stagger the release time, because you don't want the them all getting extended or whatever they decide to do then.
I could see them holding back BCV or BWV(not both), and maintaining it for cash reservations, as I think there is enough demand to get 90% cash reservations without risk. I think it's very true for BCV.
I know towers aren't well loved, but I also see another tower occupying at least a partial footprint of a current
DVC epcot location. I don't think they are worried about a tower obscuring our view of the Swan or Dolphin.
