I think this is an issue for the land more generally and I probably beat this perspective into the ground already when a Lion King land was still a rumour. In short, it always struck me as an odd choice as the world of the film does not include any manmade structures, or humans at all. Whether they can turn a landscape of rocks, vegetation, and hills and mountains into something compelling remains to be seen as it will be difficult to replicate the grandeur of the African savannah and the animals that inhabit it in the film.
For example, Kilimanjaro Safaris is a great work of imagineering that recreates the kind of landscapes in which Lion King is set. However, I am not sure that wandering around it without the animals would feel as compelling or transportive as do the other lands in the park. I'm also a little curious as to how they handle live entertainment as, technically, there are no humans in the world of the film, but will they just ignore that and, for example, have African musical groups performing? In other words, how much can they "augment" the world of the film before the land looses the pretence of even taking you into it rather than just "Africa" which they have already kind of done next door.
