I think the same thing - I am very surprised that they haven't build more DVC in California. The only DVC at DLR is about 70 units at the Grand Californian. I would think DVC would sell very well in California as there are a TON of "locals" that would want points for multiple shorter stays. (I'm thinking those that live in California but not close enough to go for just the day.) With DVC in Florida now built at every single Deluxe resort (with the Poly coming soon), it seems like it's time to get something in California.
There WILL be another
Disneyland DVC...but not until Aulani is closer to being sold-out.
DVC doesn't want to create a situation where a DL-based resort option is in direction competition with Aulani for sales. Aulani cost somewhere in the neighborhood of $800 million to develop. And the DVC component is significant--at nearly 500 villas it's larger than Old Key West, Bay Lake Tower and Boardwalk.
Build a DL DVC now and every sale there is potentially a lost Aulani sale. The longer DVC has to keep marketing & selling Aulani, the more expenses they have attached to that project. If they can sell all of Aulani in 8 years (just to pick a number), it will be more profitable than if it takes 10 years or 12 years.
There are also more politics involved in DL construction since land is at a premium. The use of every square foot is scrutinized to the Nth degree because of the value of the land and its scarcity.
WDW has 30,000 hotel rooms and thousands of undeveloped acres. Compared to DL, it's a cakewalk to gain approval for new construction or DVC room conversions at WDW.
I don't see anything which suggests Disney has a need for, or an interest in, building regional DVCs. That said what about building some kind of DVC near foreign Disney theme parks? I have no doubt many current DVC owners would like to stay at a DVC near DLP but I question how many guests would purchase points at such a resort.
I don't know how you want to define "regional" but Aulani was a very significant non-park investment.
At this time, Disney hasn't shown any interest in creating many regional properties. That could eventually change...time will tell.
If Disney wishes to continue supporting the DVC business model, they will have to change their approach in the next few years. Dating back to the mid-90s, DVC's approach has largely been to add-on to existing WDW hotels or convert older properties (Disney Institute / Saratoga) to villas.
Grand Floridian will be sold-out by 2015. Poly will probably be gone by 2018. There are a few projects under consideration...a second tower at Contemporary, a building at Ft. Wilderness, possibly some units at Yacht Club. And they could always build a brand new resort (although it's an approach they haven't used in nearly 20 years.)
But from 2018 to 2042, they have about 24 years before first-gen resorts like BoardWalk and Beach Club start reverting back to Disney ownership to be renovated and re-sold. 24 years is a lot of time to fill with new construction if they wish to keep the DVC revenues coming in. The first 24 years of DVC brought 12 resorts and about 5000 villas.
DVC may need to start looking outside of the parks again both to broaden the appeal of the system--attract more buyers who do not want to visit the theme parks every single year. Aulani added a lot of value to the entire system. Other popular tourist destinations would do likewise. DC would have been nice to have on the list...it's a shame Disney bailed on that (although I read a lot of criticism over the specific location of that land in National Harbor.)
International parks may be an option, but there needs to be a viable market among buyers who are within close proximity to those resorts. There simply will not be a lot of US buyers for a timeshare at Disneyland Paris or Tokyo Disneyland. Few people will get there often enough to make it a worthwhile purchase.
Those international resorts also have issues with land scarcity (cost) and the ownership situations are much more complicated than DL and WDW.
