You can name other Disney or Pixar related films if you want, but I've got questions regarding aspects of WALL-E and The Incredibles that are ideal for a sequel to answer.
Inexplicable ranting... I'd rather not have to turn to a comic strip or the like to find those answers. Maybe y'all have seen me skulking around denouncing the relationships between different forms of media, but I tend to prefer a followthrough in the same media format that I originally observed the story in. If there are other parts of the overall story that are told in other media aspects, I'm perfectly fine with them being alluded to in a sequel even if it is not directly related to them. On the other hand, if there is no such allusion, I would then disregard the other media format as non-canon regardless of "word of God."
Another rant: I tend to separate the stories of most anime and their manga version. I don't regard one as better than the other but I won't combine the canon either. Trigun for example, I consider Wolfwood to be Wolfwood in the anime and the Chapel Impostor in the manga, while I also consider Chapel the Evergreen and Caine the Longshot to be canon members of the Gung-ho Guns in the anime whereas in the manga, I accept that Chapel is the leader of the Eye of Michael and Elendira is the final member of the Gung-ho Guns. There is one case in this particular story for which I prefer the manga version. Zazie the Beast is far more interesting in the manga than in the anime.
