My statement was based on pure math & ignored other factors - when fully sold there’ll be about 6.5 million Riviera points in non DVC ownership. If 10% of those points hit the resale market that’s 650,000 points changing hands, figuring an average 150 point contract that’s 4333 listings. A couple of years ago Riviera was half sold - 10% of 3.25 million points is 325,000 points which w/ an average of 150 points per resale contract equals 2166 listings or 1/2 the supply as will be available when the resort is fully sold. There are other factors of course, most of which we really don’t know.
I don’t know if you were in the market for DVC during the downturn following the 2008 housing crisis, but DVC did not use ROFR to prop up resale prices, resale prices fell & DVC didn’t buy them. That was the Wild West!
Maybe Riviera will be that one unique resort & DVC will use ROFR to buy back points figuring they’ll turn a profit, but I’ve not seen them do so w/ other resorts, so I doubt it.
Riviera has been on sale for 6 or 7 years & will likely take 9 years to sell out. By then Poly2 will be nearing the end of direct sales & Lakeshore Lodge will be just starting sales. There’ll likely be another DVC resort gearing up for construction - maybe Riviera Tower 2, BLT tower 2, Epcot front of park, something over by DHS, another Skyliner over to AK/Coronado Springs + DVC’s Coronado tower

who knows. Following the next 2 or 3 DVC resorts there’ll be the new versions of BC & BWV - both walkable to 2 parks + whatever they’re going to do w/ the unextended OKW contracts.
IME DVC focuses on selling new resorts w/ occasional sporadic bursts of ROFRing an existing resort to flesh out their portfolio or offer special short term sales, or to grab points they need to cover their 2% when they sell a few more points than expected (which I suspect happened w/ VGF2) so I’d be surprised to see them behave differently & start consistently ROFRing Riv. after it finally sells out as a sort of side hustle from selling the shiny newest DVC resort which may or may not be a part of their new trust version of DVC ownership.
