I know you said no debate but because of the way the land lease is written, an extension extends all points regardless of opt in. And it maintains the
point chart and association status.
Based on the legalities and the direction of
DVC, it is much more likely a new association begins on 2/1/2042. Existing owners are given a chance to buy back in with a discount. The resorts rejoin the association on new rules. All buyers of the "extension" (which is what it will be called, even though legally everyone will be on a new contract in a new association) will be considered direct purchasers for whatever value that has at that time.
