There was a rumor that involved some changes to that area. Frontierland expansion actually however those plans faltered when they decided to update Tomorrowland instead.Is that a rumor? I would be ok with an upgrade but hope they don't totally get rid of it. With the utilidoors there are a lot of areas of MK that are a lot of concrete/not much plant life so I appreciate the island in Frontierland
I don't see them totally getting rid of it at least anytime soon.
