IMO that's overly optimistic. First it may not happen and second, if it does, it'll likely approach or pass equivalent retail pricing.
I don't see the owned vs RTU as a big deal either way in general but it likely is an issue for the 2042 resorts.
Corporate DVC is very smart at marketing .... and will look HARD at making an offer to extend an original OWNER or direct family member's DVC expiring ownership by RESELLING the points back to them. If the original family brought at $35 per point and the offer to extend is $XXX per point (where DVC has spent almost no DOLLARS on marketing or commissions send a new certificate and update the computer records) verse selling those points for say, $XXX per point ... DVC would do fine. And I am not saying that the exact terms of ownership would NOT be absolutely the same as the original certificate. DVC might require a additional full price purchase ALSO ... so a
123 point contract might have to be upgraded to a
231 point contract. And/or DVC might alter (increase the number of) points required to book resorts & unit sizes.
I do NOT see DVC saying "Farewell, Good bye" to these very long term DVC families who owned their points for 15 or 20 or 25 plus years .... esp if prices drop on the resale market as the expiration dates approach the "Drop Dead" date.
Disney is NOT going to tear down all the DVC resorts ... could seriously remodel or alter the theme of resorts which could be due to outdated theme park, outdated design (handicap or maintenance issues), structural issues of a building, etc. The Animal Kingdom Park is a big land hog and very expensive to operate ... and part of the DVC resort theme... could be either expanded or just totally terminated. Or the Contemporary Resort (the oldest hotel?) with the monorail running thru it ... on that expensive real estate next to the Magic Kingdom.
The Orlando park opened in 1971 .... designed in the 1960s. I was living 35 miles from NORTH of the parks for over a year when Disney dropped the rope. Things CHANGED drastically in Central Florida after October, 1971 ... not so much in 1971 or the following couple of years ... but the area drastically was altered within 5 years...new interstates, local roads, airports, schools, towns built. Orlando Airport is NOT MCO (was McCoy Air Force Base in 1971)... Orlando Airport today services mostly private planes. The larger airport for that area in 1970 was Daytona Beach International Airport ... still there with a commercial flight or two daily ... but TODAY most flights are due to Emory Riddle University which sits with direct access to the runways... a school which has expanded from its 1971 days...when I dated a Vietnam vet going to school there.
Almost 46 years for WDW Magic Kingdom Park ... less for the oldest DVC resort incantation... I am sure changes will happen ... if I really, really knew the future for the DVC resorts .. I could make a fortune. Meanwhile, I will just keep using my 90 DVC/AKV points.
