Let's suppose Disney isn't opening anything new for the next 5-6 years at DHS. What on Earth are they going to do with that park over the next five years? As much as they want it to, the Frozen Summer Fun isn't going to sustain that park for too long, even with a sequel on the works. I know they are closing attractions that are not super popular, but they're still experiences that take people away from the main rides and add some extra stuff to do during the day.
I say phased openings are going to happen at Star Wars land.
