There were rumors that one was in development, incorporating a large robotic arm that would lift a ride vehicle off of the ground and act like a motion simulator. However, apparently WDI lost the rights to use the arm in attractions where it isn't already present (like a smaller version in The Seas with Nemo and Friends for the anglerfish).
Currently, the Incredibles characters do a meet and greet at the end of the Animation Tour at MGM, and also appear in Block Party Bash, the parade at Disney's California Adventure.
