I have not seen anything out front of the entrance to US, however CityWalk has a large Pharaoh Hound type of guard statue and mini set advertising Revenge Of The Mummy.
Mostly movie themes, was just posting bout this a little while ago on another board. Like Beetlejuice, BTTF, and I and another poster are pretty sure we heard Superman's theme, can't rem anymore currently. The only other things I can think of that might be new to you would be the Street Breakz break dancing show(I really enjoy the show and have alot of respect for the performers) As you mentioned ROTM and it's gift shop, new characters from the Mummy for photo ops, and also a little gift shop around the corner called Second Hand Rose reopened. That's all I can think of, sure I'm missing something
