Well, that was the Japanese version. (The title screen and option menu is in English, voice acting is in English, and you can choose between Japanese and English subtitles, as well as Japanese, English, and Korean in-game text.)

Personally I have no problem whatsoever playing a "Japanese" game like that. The NA version should be out in a few weeks I think. Seriously though, if you like either of the first two, you will like this one.
