Remember, Disney wants a new
DVC to sell every 2-3 years. If they had it to do all over again, they would have staggered the older resorts and not have them all expire in 2042.
Note -- Through ROFR, they are slowly accumulating 2042 points. They have been ROFRing more points than they are directly selling. I'm not sure of their motive, but it appears they might want to reduce the number of points out there as we move closer to 2042.
So some speculation -- They won't just start selling new contracts for BCV, BWV, OKW, and BRV all at once in 2042.
OKW -- will just keep selling with 2057 contracts.
Between the other 3 resorts, don't be surprised if we see something like:
1 of the resorts immediately turned around with new 2092 contracts.
1 of the resorts undergo a massive refurb, even possible re-build, not go on sale until 2043-2044, with 2093-2094 contracts.
1 of the resorts get totally levelled, re-purposed, completely replaced.
For example, I could see BWV simply continued after a basic refurb..
Beach Club massive re-construct, with views into Epcot, far more rooms, etc.
Boulder Ridge levelled with the land re-purposed as a whole new resort or something entirely different.
I wouldn't expect any major perk to expiring owners, except maybe a little bit of an incentive towards a new contract at whatever resorts have open sales.
