I wouldn't count on it. Most likely guests will arrive at the JW park in Chaos Theory mode by some spawning point in the park. I don't know if they will go with the old monorail system again. I doubt it.
I also doubt you will be seeing the Brachiosaurus scene from JP cause that would be very hard to set up in this game since nothing is scripted. They can probably script things for the screen shots and videos. But not in the actual game we will be playing.
