I just talked to a DVC sales person at DTD in CA and he said they were supposed to hear something about a CA DVC in four weeks. Don't know if that is old or new news, but it was new to me.
DVC has had sales offices at Disney Land for about a year now. So the rumors have been hot & heavy about a California property. If the person you talked to at DTD knew what he was talking about, and they frequently don't, it would certainly be news.
I would love to see DVC construction at DL and would definately book it should it ever be built.
Disney originally purchased property in Newport Beach, CA in 1994 for a DVC project. Unfortunately, the project was canceled a few years later. The property was sold and is now the site of a Marriott Vacation Club timeshare.
Hopefully, Disney will do a DL site in the not too distant future.
