I must admit, I'm relieved to see that the Imagineers have shown such restrain in their new colour scheme. It works well, in my opinion. Now I'm just not sure how well the new logo will fit in. Or the proposed statue of Buzz at the entrance.
The actual logo doesn't have to be on the facade. WDI history has shown many, many examples of logos that were not actually used on the attraction building for aesthetic reasons. An appropriate font will do.
