Is there any chance that the removal of the "dome thingy" could be a start to integrate Tron into the entire land? The aesthetic, colors, and feel of the Tron canopy could really bring some life to the rest of Tomorrowland.
Currently adding Tron to the area gives us at least 3 distinct looks for a land that should be cohesive. (The awful mechanical look, the contemporary style of Space Mountain, and then the "flowing/digital" look of Tron).
I watched a video somewhere on youtube, which said that is the intention.
