So my opinion is "No", and I doubt it will every be an immediate burst.
If you think about where these resorts SHOULD be priced, it should sort of be based on the sales of resorts that are near 50 years. A great place to make this comparison is with Copper Creek and Boulder Ridge.
Copper Creek runs in the $150 average price while Boulder Ridge is running in the high nineties, lets call it $95 per point.
If we consider Copper Creek with 45 years left and Boulder Ridge with 19, all else being equal you are paying $3.33 / point / year for Copper Creek and $5 / point / year at Boulder Ridge.
Boardwalk is similarly going at $115 a point and Beach Club around $140 a point versus say BLT at $160 per point. That puts Beach Club at $7.27 / point / year and Boardwalk at $6.05 / point / year vs BLT at $4.32 / point / year.
Even OKW 2042, while running at some of it's lowest price in years, seems to still be around $90 / point, or $4.73 per point. That's comparable to direct pricing of Riviera, which at $217 is $4.62 per point.
So while these prices have settled down a bit, they are still inflated against what the market SHOULD be.
I look at the less favored resorts should be running around $3.50 / point / year remaining, while more favored resort are around $5.00 / point / year remaining. IMO Beach Club and Boardwalk should really be priced around $100 per point, while OKW and Boulder Ridge should be closer to $70 per point IMO. So I don't think we have yet reached a point where the bubble burst.
I would really expect we will see a steep drop in prices for these resorts in the next 10 years, but it wouldn't surprise me if they stay inflated due to people wanting bargains. In all honestly, I've been saying for a while, if my Boardwalk contract is still worth near $100 a point with 10 years to go, I will sell it and take the cash and buy at a longer lasting resort. (I paid $105 / point in 2017.) By 2032 these resorts SHOULD be selling for $60-70 per point.
