As the one who said "well I've heard this", I want to clarify a little bit. I have heard it that an attraction and dining experience is a plan for a possible expansion. It has not been approved yet of course and it may never be. Personally Pandora could use another attraction to help the take the load off the current two rides but then again there is so much going on or coming to WDW I don't know if they would be so quick to add it.Vulture said it. Other sites are repeating what Vulture said. So, I wouldn't characterize one source as swirling. Unless you know of another site that has a source that isn't linked back to Vulture?
However, one of our insiders said an enigmatic "well I've heard this." So, maybe maybe?
