I rather see a sequel, but not like the figure of Incredible incorporated because it will show a world where heroes can appear on scene again, and that's the opposite that the pixar theory says. I think that the new movie will show the have been forgotten that superheroes, and the technology is their new source of trust to feel safe and even happy. Now everybody can be a hero. I believe more in the theory that Jack Jack will be the villain because he is to powerful and he lose the control of him self. It will be interesting how his brothers and technology will control him.
