Over the weekend, D23’s Destination D event revealed a couple surprises. One of them was a new prototype for the Disney bus transportation system, the Sorcerer Class Concept Bus. The bus had a light feature near the roof that changed colors to coordinate with an audio soundtrack of promotional content. No information was given on when these buses might debut or whether the audio content would provide some form of entertainment (instead of commercials) once they did make their debut. Rather, the prototype was simply on display to show the type of technology available and how it might be utilized in the future to make the guest experience with Disney transportation different than others.
