Imagine this third park - DISNEY ACQUISITION ADVENTURE
You enter through PIXAR PLAZA where homage to all things Pixar can be found. This plaza funnels guests to a central "hub" of sorts - a giant Corporate boardroom and there are multiple exits - one leads to OZ LAND. Another leads to LUCASFILMLAND where there is a Star Wars and Possible continuation of Indiana Jones. Near that exit is MARVEL UNIVERSE which is a land based on... well isn't it obvious? Next exit leads to MUPPETLAND!
The mind reels at all the possibilities.
