There are 6 groups of owners that expire in 2042:
OKW non extended
Vero Beach
Hilton Head
BRV
BWV
BCV
DVC can't let them all expire at once, for several reasons.
1. It would create absolute chaos in the last few years to have that many owners trying to cash out final points. It would make the 7 month bookings unusable for years and the 11 month bookings at those resorts the same.
2. It seems pretty clear now that the model DVC wants to follow is CCV/BRV. 2 RTUs 25 years apart. But. If DVC lets multiple resorts expire simultaneously, then they'd have to be resellling something like 4 resorts at the same time. No. Ultimately, I think DVC would love to be reselling its resorts every 25 years, but to do so, they must put them on a rotation.
3. If DVC is looking for a 25 year model, then the first resort to be resold in 2042 will be BRV. All the others will need to be moved out a few years based on their 25 year windows. After Riviera, expect DVC to go back into BWV or BCV to create a new timeshare, and then extend the current RTU to 25 years out from there. For example, Riviera in 2019, let's say BWV2 in 2021. Then BWV1 will be extended until 2046. This will be absolutely necessary to stagger end dates so as not to have to be reselling multiple points at once.
4. It's widely expected that DVC will toss out VB and HH in 2042. But again, what do you do with all those owners? Someway, you have to get them back into the system. It's an awful business model to kiss a group of customers off. My guess is that they stagger those end dates across two sets of new resorts expiring (say 2042 and 2044) and offer a decent discount for current owners to buy into the currently selling resorts (say $25/point discount). That means they'd close one in 2042 and offer a discount on BRV and close the 2nd in 2044 and offer a discount on Riviera2. So 1 of the two might get a 2 yr reprieve.
If DVC planned to phase out of business in 2042, then a set RTU would make sense. They don't.
In order to keep all its balls in the air at once, only one or two can be in the hand (due to expire) at a time. DVC will have to extend a few resorts a few years to stagger end dates.
If you push aside VB and HH for a moment as resorts not likely to be 25 year splits, and OKW as likely to be pushed 15 years down the road because of its previous extension, and BRV as already completed with CCV as a 25 year split, then my guess would be:
2019 Riviera
2021 BWV2 (with BWV1 extended until 2046)
2025 another new resort.
2027 BCV2 (with BCV1 extended until 2052)
2029 SSR2 (with SSR1 expiring on time in 2054).
(There'll be a traffic jam for 2057 with OKW and AKV that can't be fixed by extending out because VGC and BLT occupy 2060.)
I think there are reasons why BWV will go ahead of BCV including size of resort, need to address
point chart sooner (BWV is too cheap per night), and proximity to DHS for Star Wars.
My theory adequately staggers end dates. If DVC operated on that theory:
BRV - no extension (but likely a discount on BRV2 (or VWL3 if you prefer))
VB - likely no extension
HH - 2 year extension to stagger end date.
BWV - 4 year extension
BCV - 10 year extension
OKW - 15 year extension (they'll eventually have to figure out how to put all owners on one RTU).
