The Gran Fiesta Tour Starring the Three Caballeros is rumored to be adding animatronics to the final scene.
The animatronics are reportedly on site and were originally in the Mickey Mouse Review show that previously occupied the building that currently houses Mickey's PhilharMagic. The Mickey Mouse Review show was transported to Tokyo Disneyland and when the show closed the Three Caballeros animatronics were sent to Epcot. The delay is the funding required for installation.
