Looking over this survey it seems like it could only apply to the purchase of new points at new resorts within the new trust model. I think we will hear more about this when Lakeside opens since it will likely be the first time two resorts are in the trust. Since your contract doesn't attach you to a room anymore, I wonder if it really even attaches you to a resort. Perhaps they are going to give trust members access to all trust resorts with priority access based on trust points owned. I'm not sure of the legality, I think it's legal from what I've read, but
DVC could stop selling direct to existing resorts and instead sell those contracts to the trust allowing them to charge trust members a fee to access the home resort priority of the points owned by the trust. The 7 months would still be open to any direct member.
I'm not sure how much can or will really change with the existing resorts, but I think a lot could change for future resorts and as resorts get more contract turnover. The big question mark everyone has is what happens after 50 years, it seems like if the trust doesn't have any attached resorts it solves that problem by allowing them to kill the cabins early if they don't sell well and shifting those trusted points to the vacated Saratoga Resort when the deeded contracts end. They can sell 50 year contracts every day and they always have full value with complete flexibility as long as DVC can provide rooms to back the points.
