Depending on what game(s) they have in the pipeline to start once BG3 is 'done', if they see a big enough push for modules they might be financially swayed to do an official one. What I mean is that if they see a massive surge in modding and huge population of people playing those mods, and IF they judge that it would be financially worth it for them to spare the resources to create a module, like Storm King's Thunder, then I could see them doing it. It shouldn't take them anywhere near as long to make as the base game because they wouldn't need to create any new systems, though they would have to create new models for creatures/monsters they haven't built yet, the whole world for the mod, voice acting, so it still wouldn't be 'quick' but shouldn't take as long as the base game took.
Nothing I disagree with, though I think it would be a shame if the cost of creating official modules ended up being too much because of voice acting and Cinematics. Nice features, but completely expendable (user made content won’t have them, of course).
