I think Whylightbulb is lying.
I honestly can't see Country Bear Jamboree being removed from WDW because country music is an institution in Florida. When you have a county ( Osceola, not quite Orange, but right next door) that gives students the day off on the first day that the Silver Spurs Rodeo comes to town, country is taken VERY seriously.
In addition, the theater is almost never more than half empty and the space that the CBJ occupies at WDW is way too small for something else to go in its place anyway.
I can see them adding an interactive Next-Gen-style queue to CBJ, but not a complete removal.
Granted, I was there last September so it may have been fixed since then, but the audio quality was deplorable. Several of the speakers didn't even seem to be working.
I love the attraction and hope the poor state of the show isn't indicative that it is on its last days.
