If I owned at one of the 2042 resorts I'd be looking to sell today and rebuy at one of the 2060+ resorts. Sure you could wait another 10 years to see how it plays out, but what happens if in 2030 its announced that in fact your deed will expire with no extension or other options? That was the original deal anyway. The closer you get to that day the less options you have and the more time decay you are going to suffer, similar to stock options. I think the price / point delta between the 42 and 60+ resorts is going to increase in the coming years due to these factors.
Points are lower resale right now so you'll take a hit selling, but you'll make it up rebuying. This was one of the major deciding factors when we bought CCV a few years ago, and we cant be the only ones thinking that way.
