I would think for USF and IOA, both have now ditched the "ride the movie" aspect of USF and then the Literature aspect of IOA with Kong at IOA and as you said, Fallon; Simpsons; and even SpongeBob.
Nintendo? You have countless IP's that with fine tuning, can easily be translated to multiple lands across the entire resort. It's the next Potter, and that Universal would be dumb to not have Nintendo fleshed out the Potter way as opposed to restricting it to just one park. And that I am open to it with fully acknowledging what Universal Studios Florida and IOA's original purposes is dead.

That said, I am going to guess that they could close Curious George and Barney first in Janruary, and keep Animal Actors, Fivel, and Woody Woodpecker until after Mardi Gras.
