Disney and DVC always has many suggestions on the table for consideration. With DVC, I doubt there are many possible resort sites they have NOT considered.
Depending on who has been privvy to the actual discussion, the possible sites (like AKL, CR, Poly, GF, Venetian- the ground on the monorail between CR and TTS) have been unintentionally (or intentially) leaked - even though no serious consideration ever took place (just a mention in a brainstorming session). When another CM gets wind that one of these site was "discussed in the meeting" it suddenly becomes the next location and is fair game for the rumor mill.
At this time there have been "official" announcements of the site in Newport, CA (later scrapped and the land sold to another timeshare developer), land was owned in Colorado and a resort was to be built in NYC. All later fell by the wayside, with no particular announcement.
The Eagle Pines project (no name for the resort was ever announced) was "officially" released- including artist renderings and has not ever been declared dead. The rumored supsicion is that it is still a viable project but, just as with SSR, something else could still be offered before that ever is built. Eagle Pines will still require a lot of infrastructure (roadways, utilities, common areas, etc.)- which was an advantage at SSR since many of those were already in place. A CR project would likely have similar advantages, as long as the other obstacles could be overcome.
Stay Tuned!
