Bob Iger since day one has had a personal bias in favor of the studios. He views the theme parks (and video games, and books, etc.) as basically a tool for and extension of the studios in the same vein as merchandise, not understanding and taking advantage of the fact that themed entertainment is a storytelling medium by its very nature. He literally reorganized the company around his flawed perception. In Bob Iger's synergy chart, all arrows point outward from the studios, which is unhealthy for every other division.
Take Disney Infinity for example. It was plenty profitable, but the studio heads deemed it was hurting their integrity, and so they wanted to end it, and Bob Iger listened. The studio heads ended Jedi Mickey and gang, Star Wars Weekend elements, a Tiny Tower spinoff called Tiny Death Star, etc. too for the same reasons. Even though the video-game-related decisions basically killed the division, my point is not to criticize these decisions, rather it's to point out his clear bias.
Would Bob Iger ever allow the parks, or any non-studio entity, to get rid of something profitable if they deemed it was hurting their integrity?
