Edain already reached a full english version after many years of anguish, because english isn't the primary (and not even the secondary) language for many team members. Nonetheless, a huge effort from the team and community was put to make it finally in English.
However, I wouldn't put much hope in any other language as finding other strong language bases (say spanish) among community and most importantly the team, is highly questionable (you can't really make a mod if you don't even understand what's in it).
I do believe that the team announced at some time that no languages will be supported other than German and English.
A free community group can still translate the mod to their language, but they won't have any official support from the team.
