It undoubtedly has had a non-zero impact (there's surely at least one truthful post on this forum of someone saying it was the reason they didn't purchase), the better question is how much--is it that one person or is it bigger?
I'm not nearly as pessimistic as many in this thread, but I fully expect it eventually to have a casually noticeable impact. Something like a 5-20% drop relative to expectation (based on the merits of RIV/future resorts themselves).
The intention of these restrictions is to deflate resale prices. RIV resale points have a different value compared to resale from other resorts due to their exclusive use. Exclusive use is/will be a dealbreaker to some people, even if they love RIV as a resort. Potential resale customers opting out is, by definition, a reduction in resale demand and assuming resales supply is unchanged, reduced demand means reduced resale prices. In turn, that impact on resale should cause a smaller but non-zero impact on direct sales velocity.
I'm not sure any of us can currently say how much it has/will reduce resales prices with hard data considering there haven't been many resales. But it's extremely unlikely to be 0% impact considering how well informed resale buyers are (on average). The good news is that, so far, it doesn't seem like resale is completely devalued and seems very loosely in the ballpark of other resorts.
As for the impact to direct sales velocity, that likely requires internal data, and I'm not sure even Disney could precisely determine the impact amidst all the economic volatility from the pandemic. They probably have a ballpark idea from surveys, though.
A likely long game for Disney is a slight deflation of resale prices so they:
- Don't significantly hurt upfront sales velocities/prices
- Maintain some semblance of good guest satisfaction levels overall, likely including value retention as well
- Put themselves in a position to more easily repurchase the contracts on ROFR
- While keeping their own longterm/sold out pricing at an optimal price point without eating into the resales margin ($200/pt sells better than $225/pt).
- Also keep in mind the 'resale' points they sell are better points because they can be used anywhere, so they have a better product to help justify their higher price.
Considering RIV hasn't sold out yet and resales are still a trickle, they probably can't see if 3/4 are going to work for them yet and I'd be surprised if we saw any deviation from the plan for VDH.
