Nope, nothing new. The "facility exclusively for Ft. Wilderness" rumor died down. Honestly, I never understood that one. If it wasn't supported by the revenue it took in, why would anyone think it would switch to "free"? The number of CM's required is quite large.
If you do a search, you will find an old threrad posted a few months ago here on the rumors board that offers pictures of River Country in its current abandoned state. Judging from its current condition, I don't think Disney has any plans to repoen this again.
