Read both of these rumors as well.
At River Country there are landscaping stakes. Someone found some architectural designs on the internet for a possible building here. On the Camping board, there were several posts about it. Additionally, several people have reported that some FW buildings will be moved this summer.
The CSR area rumor was based on an firm's internet posting that they had drawn up designs for a California theme DVC between BB and DHS. It was noted that this firm's advertising also listed DVC properties that were never built or were sold off.
I'm also wondering how long it takes to build a DVC resort.
I've read reports that it typically takes 2.5-3 years.
Even with construction, Disney could sell off the building. I believe Disney did sell off the property rather than make it part of DVC.
Until DVD starts selling points in a new resort, plans could always change.
