Ni no Kuni is coming to North America and Europe in Q1 of 2013, Namco Bandai has confirmed today.
With complete language support for each territory, it seems like quite the effort is going into Level-5's newest RPG. In addition, the game will contain both Japanese and English audio options.
An English trailer was shown at the event with characters sporting a variety of accents including American and English. We hope to have it available for you soon.
