I agree that Disney probably wouldn't invest in a movie that didn't do well or isn't that popular - of course they are building a new Tron roller coaster, so you never know. (I'm kind of surprised that they didn't put Tron into Epcot, it seems like it would fit the theme better). Also, you never know if someday Disney might try to remake, or add a sequel to some of their older movies - BOLT 2 for example (I doubt it, but again, you never know). Maybe Disney will really throw us a curve ball and make a Black Cauldron dark ride.
