We will just have to see. If Disney is truly thinking about turning Indiana Jones into an "expanded franchise universe", it might be interesting and good. I'm imagining a whole new 1930s universe in which we are introduced to a gang of romantic rough-hewn characters, some of whom we've already met (the tramp steamer captain, Indy's seaplane flying pal, the hard drinking beautiful saloon keeper, etc.) all fighting in a loosely coordinated effort dedicated to undermining the Nazis. Of course, there would have to be something tying them together and presumably that would be their relationship to Dr. Jones. But he wouldn't necessarily have to make a cameo appearance in each film. As long as Disney stays true to the 1930s mythology/style/conventions and some of the Indiana Jones iconography, I'd be on board for the ride. So I'm not yet writing off the whole enterprise. Although ---as of today--- I've seen nothing additional to confirm that Disney is really working on an "expanded franchise universe" concept.
