Why doesn't console version has the same languages available as the PC (Steam) version?

Hi! I bought Moons of Madness for Xbox yesterday, and i was disappointed when I saw that the game was in English. The game for PC is available in my language (Brazilian portuguese) since it was released. There is a lot complaint and low rating in Xbox store for this reason.

Why is still not available? It’s very unusual the same game being selled for more than one platform having translations available only for pc
