Yeah, I'll have to agree and say either Despicable Me or King Kong. Despicable Me just makes more sense at this time considering the first one was a huge hit for Uni, and there are plans for sequels. Plus, I don't think they would scrap a kids ride and replace it with something less kid-oriented like Kong. Theres not many kids rides there to begin with, so I would think if they are getting rid of one, they would replace it with one, which would make Despicable Me the frontrunner here.
Update: Then again, take a good look a the window, it almost seems like there is some sort of face, which to me could look like King Kong? I don't know. But I'm definitely looking forward to the next clue.
