Mark Willard is reporting on twitter that this along with the rebel hangar have been tests to start moving to more random atmosphere and less static meet n greets.
Note that Mary Poppins and Snow White have moved from their town square areas to the hub - my money would be on them to be next. He also said part of this is to save money on attendants. Like DL has been doing all along...
If this takes hold it will be a seismic shift. Maybe one day we can reclaim some of this prime real estate that has been handed over to meet n greets
