I still think that's a really messy way to "retcon" something without the actual retcon, and if that ends up going to be a thing that happens, they'll have to really come up with a clever way to do it, although it'd still be at the risk of ticking some people off. (To be frank, anything that's going to happen will tick someone off one way or another. Can't please everyone.) One of the points of Tri is to show the difficulties knowledge of Digimon in the real world bring up, which in turn leads up to the epilogue. Shipping scorns aside, the careers chosen by the kids have been another thing people didn't like, and so I can imagine the movies might show this process in the kids deciding what to do when they enter adulthood (Joe already knows what he's going to do, but we might still see that struggle). At the very least, we're getting this with Tai; the movies appear to be a coming-of-age story, and Tai's choice to become a diplomat had to have been the result of some kind of personal epiphany. But even so, if alternative universes are going to play a role in the movies, I imagine they'll show more cons than pros in terms of the characters.
