I honestly hope they just replace the animal actors show completely with another family friendly show down the line. It's not as entertaining as it used to be, and I feel that they could use the space for something else, especially since it's an eyesore. But for now, I think it'll stay. Crowds still fill the space and it's relatively cheap to run.
I'd rather they focus on replacing other things in the park first. But I agree that they should at least improve that exterior.
