The offending article

Level-5 and Studio Ghibli collaboration Ni No Kuni is getting an English release on PS3 in 2013, but its DS counterpart won't be leaving Japan. Level-5 CEO Akihiro Hino explained to Famitsu (via Andriasang) some of the difficulties preventing the portable adventure reaching the West.

The DS game comes with a large Magic Master book, as seen in this video, which would prove difficult to localise for other languages. Ni No Kuni: Wrath of the White Witch on PS3 features a digital version of the book, so skips out the cost of reproducing such a lush tome.

Sadly it looks like DS owners in Europe and North America won't ever get to experience Level-5 and Studio Ghibli's acclaimed adventure, which is a grand old shame indeed.
