Since no operators have taken Disney up on this venture, I have to continue to assume that this is a bust.
Which venture is a bust?
You have no way of knowing who is lined up for DS. Just because they haven't announced any tenants, doesn't mean there aren't any. There's no way they would plan, and move forward with, this expansion if a huge portion weren't already leased or promised.
As for FC, it's more than a bust. It's dead as a doornail and has been for years. That doesn't mean it always will be however. It's a good idea, and eventually it will happen.
