Looking at the spot at 51 seconds and with no first hand proof, this is what I see. The weird S path cleared on the front "island" I would say that leaving the trees there had no real purpose if they were going to take them out later. It does, however, kind of fit in with the ride path plans that we have seen including the "fun" one.
Also the fact the the old riverboat loading area still exists and the strange jut out toward the river might mean that they are going to use that building as an exit or entrance to that land. The plan below show a building in that approximate area, but it would look different that the original. Just guessing you understand, but it is suspicious to my eye. As I look a little closer I see that the gray building seems to already exist. How about maybe a picture site overlooking the projected waterfalls.
