At most, owners of 2042 resorts will be on the hook for only 1/12 of the costs of operating their resort in 2042, since dues are assessed based on calendar year. They won’t be responsible for contributing to any capital reserves, either. So I wouldn’t be surprised if DVC rolled the January 2042 member fees into the 2041 assessment.
I expect DVC will modify the banking, borrowing and possibly the non-owner booking rules the last few years in order to allow owners the maximum amount of time to use their points. I’m sure they recognize that December UY owners, for instance, are likely to want to borrow their 2041 points. OTOH I’m hoping I’ll still be alive so that I can use all my September 2041 points for a BW view villa in January 2042, with the last night being January 31, 2042!
