I do agree that Tomorrowland should be a much larger priority, but it probably won't be until we get someone new running the parks again.
Of course Disney has to be careful with the changes as well, they have eliminated a lot of entertainment while Knott's has been adding a lot and been moving to try to be more family friendly again so Disney may at some point find themselves being second to Knott's, especially among the locals. Now while the economy is as strong as it is right now that won't be a problem, but when it takes a nose dive, all local theme parks are going to rely very heavily on locals and passholders just to keep afloat and locals aren't going to look favorably on Disney if they get rid of too much of the history of the parks,, especially if they also have eliminated entertainment and raised prices so ridiculously high.
