This question requires a poll....
But the reality of 2042 will be very interesting. You will have several different groupings of owners:
1 -- "original owners" who were fairly young when they bought. Now, they are on the other end of the spectrum... retirees, kids all grown up.
DVC has grown much more expensive than when they bought originally. I suspect most of this group will be "done" unless they want to buy points for their kids and grandkids.
2 -- Those who inherited/received DVC from their parents (or grandparents). They may have been going to Disney for 30-40+ years by that time. Now, they have kids or possibly grandkids of their own. For those in this group with Disney-aged kids.. it may be hard to suddenly end WDW traditions overnight. This market may look to buy back into DVC. But there will be an economic divide -- Pricing of DVC has increase faster than inflation. It's not as affordable now (and in 2042), as it was in the 1990's and 2000's. Those who inherited/received DVC from their parents for free may be hesitant to pay $300+ for new direct points by 2042...
3 -- Those who bought re-sale along the way --- Of course, this group is also split between those who purchase it themselves, and those who inherited/received resale. This is a group that were bargain hunters to begin with. 2042 will present a challenge -- By then, resale will be a very different product than it has been. By then, the majority of resorts will have re-sale restrictions. So those in this group will be split:
3a -- Older members of this group are most likely to be "done"... their families have aged out of WDW, no real reason to re-invest.
3b-- Those still actively using DVC for their kids or grandkid-- will face the economic reality of whether they can afford "direct points." And if they can't afford direct points, the question of whether it's worth buying restricted re-sale points.
My guest is a minority, but significant percentage, of all 2042 owners will be in the market for new direct contracts. (Broadly speaking, I would guess 20-40%). I'd guess that about half will simply be "done." Not ready to pay a big upfront price to start all over again. Meanwhile, a portion will look for affordable re-sale contracts in a resort they like.
