Hello!
Per a post made earlier this month, David The Developer stated that Archaelund will have translations into other languages, but not for the early release set for Jan. 8, 2024. I --think-- that's to allow for translations to happen after all the game text and dialogue is finalized. That way there's only one translation wave needed.
Per several posts over the last year or so, Exiled Kingdoms is not going to have progress made while David focuses on Archaelund. Maybe some time in the future, EK might get expanded. But that might also depend on what cell phone companies (namely Apple) decide on software issues.
