Disney recently announced a plan to rename the Disney-MGM Studios theme park to Disney Hollywood Studios. The rumored motivation behind the change involves the possibility of complete overhauls to many areas around the park creating a new experience. Mickey Ave is already receiving a complete overhaul into an area currently named as Pixar Studios with a brand new attraction Toy Story Mania expected top open in 2008. Basic logic could dictate that Pixar Studios might end up extending over the the Honey I Shrunk the Kids Movie Set Adventure, which could easily be changed to tie into the Pixar film A Bug's Life. Star Tours and the Indiana Jones Epic Stunt Spectacular are close enough together to create a land dedicated to the myths from George Lucas.
Certainly a change to the themed areas of Disney-MGM Studios would mean more distinction to the different sections of the park. As it currently stands, Disney-MGM Studios is the only theme park of the four Disney World theme parks that does have distinctly different themed areas.
If all goes according to plan, the change in the name should occur around the start of the new year.
