So, it's not going to be a coaster, and it probably won't come from S&S or Huss, and they already have 2 dark rides. It probably won't be a huge thrill ride, seeing as they just got one, and it probably won't be a new kid's play thingamajig cause they've got 2 large things like that already.
Last I spoke with the management they said that they hadn't decided what they were going to do with the tree house, but they said that the landing was indeed still open and would stay that way for awhile. I'm going to put my bets on some type of revamp of the Tom Sawyer's Landing/Tree House area, maybe with some new shops and a family ride or two.
