My random thoughts:
I think the buy-in price-per-point will have to be comparable to current
DVC resorts. Otherwise, why buy at CA? -- just buy elsewhere for less and use your "cheap" points in CA at the 7 month mark. Sure, you could argue that the small size of the resort may mean that nothing will be available at the 7 month window. But that assumes there are enough people willing to pay the outrageous buy-in price. It seems to me that there is some sort of "tipping point" where, if the buy-in is too steep, people will figure out that it's better to get points elsewhere and take your chances. For that reason I think that, although the price-per-point may be more, it can't be TOO much more.
For that reason DVC also can't make the point requirements too outrageous. There would be a similar tipping point where, if it takes too many points, a DVC owner can trade out to some other timeshare to stay near DLR. Of course, if point requirements are very high compared to other DVC resorts, CA owners would have an incentive to use their points at the other resorts in order to get more nights for their points. But then that would free up 7 month booking possibilities for non-CA members.
Where I think CA will really be expensive, however, is in the annual dues. The Taxes are bound to be outrageous. Maintenance may not be as bad, since the weather isn't as harsh as Florida, but no doubt costs of labor for repair and maintenance are higher.

So my guess is that buy-in will be slightly higher, but not more than in the range of 5% to 10% higher. Same with point requirements. Annual dues, however, I would suspect will range from 50% to 100% higher.
I may be way off --

as I said these are just random thoughts. And I would be eager to hear from anyone who might have more information and/or insight than I.
