Possibly for sure, but legally, the POS states it is now a 2057 contract, which is why owners need to sign the quit claim deed so those go back to Disney.
Now, I think there will be plenty that might want to just give it back to DVD at that time, but I still think it is going to be messy for DVD to handle it and any owner who wants to still use it and pay fees might be seen as a benefit for DVD then stopping those owners from use...which means they have to cover the shortfall of all lthose contracts because IIRC, there was a lawsuit in which they agreed that owners who are extended to 2057 can not be forced to pay additional MFs to account for those contracts that were given back to Disney.
