Having received clearance from the FAA to fly drones over WDW, and to do it at night, it looks like the latest nighttime show at WDW will take off soon. This appears to be a preview of the "Starbright" holiday light show scheduled to start this holiday season.
The fact that this will be shown at Disney Springs, for free, is a bonus. But I suspect that if this goes well, more drones participation might be in store at the parks. I can see this at the still-yet-to-open Rivers of Light at DAK.
