I think your point about things being dependent on when guests from other countries start to visit again cannot be overstated.
Recent estimates are that International visitors make up 25-30% of WDW's annual visitors. They also tend to stay longer and spend more. I'd imagine that international
DVC owners have more points than the average owner, since they stay longer per visit.
Just going off of the international boards, it seems as though there are a good deal of UK, Canadian and Australian owners and those looking to buy resale. We're Canadian, looking to buy resale, and we certainly won't be buying until our borders are open again. By some estimates that could be at least another 6 months - 1 year. A lack of international buyers and guests will certainly have a big chain reaction on pricing.
