Given how crowded that area is, I highly doubt anything with an extremely high draw will be put there. It's big enough to support a lot of things, but I'm hoping they keep any additions there somewhat small to preserve the woods around the swinging bridge. The carousel from CC would fit nicely there. I assume they'll re-vamp that whole square to look nice as well, and maybe handle the crowds better.
Hmm, now that I think of it, is it possible the swinging bridge is in danger of being taken out soon? It's another non-ADA attraction, and I'm sure it's considerably more expensive to maintain and insure than it's worth to the park.
