Will the Hardcover be translated and available for german buyers in any way?

You can verify what was done for Twilight Imperium IV (preordering TI4 also allowed to gain a hardcover rulebook) just to see if there's a market. Otherwise you can verify with the German branch of Asmodee

Any News on this? I am curious, too. Even if they did it for TI4 still does not mean they do it for AH3. Also I did not see any kind of announcement on the German Asmodee site.
