Back on topic, this is something that hasn't been mentioned as a possibility I don't think: Uncharted. It would give Universal a easy response to anything Disney may do with Indy (If anything) and it could be used in some sort of Adventureland-ish area.
I also believe an Uncharted movie is in the works so they'd have that going for them as well. Naughty Dog content should easily translate to Hollywood unlike most video games. Hell, i'd love to see a The Last of Us house at HHN.
