I don't know the source (it was posted without one on WDWMAGIC) but it sounds interesting. In other news, you may have noticed a new lengthy rehab is also planned for the Liberty Tree Tavern that will see the restaurant closed for almost 5 months (July 6 to Nov. 20). I'm told that the focus of the work here isn't on the restaurant itself, but rather a complete redesign of the kitchen area that will transform it into a new multi-use kitchen area that will service not only the Liberty Tree Tavern, but an all new restaurant concept planned to open in the old Verandah space at the entrance to Adventureland. This is apparently the main reason why Tinker Bell was moved out of the building and sent to her new Main Street digs. While the concept may still be a bit fluid, the overall concept from what I understand is that it will be themed to tie into the Jungle Cruise theme. In short... imagine a crazy Adventureland themed restaurant staffed by the Jungle Cruise Captains as a way to pay the bills when they are in-between jobs, and to expand their bad comedy into the realm of the culinary arts.
I will also add that Disney has filed permits for work on the kitchen at liberty tree so that part of this rumor is confirmed. It's been said now by many sources that the second part at least the verandah opening as a restaurant is happening.
