The shift in emphasis on worldwide box office has saved the Tron franchise, and from everything I've heard, Tron is not going anywhere. The cartoon premieres soon (featuring Elijah Wood), and Disney is keen to get a sequel going. Supposedly, Tomorrowland is a top priority, but will have to wait until money from DCA starts rolling in. However, just how to approach Tomorrowland is still a big question. There are three schools of thought: emphasis should be on a Tron attraction, emphasis should be on a Marvel attraction, there is room for a major emphasis on both. I personally don't think there are enough resources to approach both at the same time (seeing as how Disney handles their budgets).
