The last few months have seen a lot of speculation regarding a new attraction, called Midway Mania, to be placed in the studio's soundstages. The huge soundstage buildings, including the Who Wants to be a Millionaire attraction, are speculated to become home to a new interactive dark ride, featuring a computer generated 3D environment, and moving vehicles, allowing riders to shoot at the environment. In short, the project is being pitched as a Buzz Lightyear's Space Ranger Spin - "The next generation".
Storylines for the attraction have been previously talked about as focused around Mickey's Milestones, but more recently, this has swung towards being based around Pixar characters, and in particular, the Toy Story characters. Each show scene would be hosted by a particular character from the Toy Story movies, complete with their own mission brief for the scene.
The time frame being talked about is to have the attraction up and running within the next 4 years.
Remember, at this time, this is speculation, and as always plans are subject to change.
