I did a book cover search once (merely curious how the other covers were designed) and Germany was the only country that published NiC. It's possible that they and other countries are just late, but I don't think that is it. From what I know:
Spain: books 1-3 (series was dropped, I think)
France: books 1-9
And many other countries are the same. My country hasn't published any but then we're still stuck with the classic fantasy genre.
