I love the speculation on what
DVC is going to do with the 2042 resorts.
One thing that I can't stop thinking about is that Disney seems to like having value for the points in the system to make the entire brand more appealing. I don't see them standing by and letting the 2042 resorts to go to zero value as what will that do to the brand?
There is also plenty of recent history showing that Disney has struggled to find the balance they wish regards to cash room bookings at some resorts and thus they convert them to DVC (CCV, VGF2 are two that come to mind).
Based on these thoughts, my completely wild guess is that at least 10 years out they will announce a renewal option for at least 20 or so years at a fairly high cost and give a larger discount the longer up front you take the extension and the more points you extend. As the years go by, the discount gets smaller. If you go to resale they ROFR the cheap points and extend them during resale. If for some reason it's a resort they are going to sale or not keep DVC, they can offer a conversion to another resort with more time left in it for a reasonable discount to give the value back in the contract as another way to not let the value go to zero.....
