The official North American release from Viz has both the English and Japanese (with English subs) language tracks, with the English being the default track (for the Japanese you have to select it from the audio menu).
America, Australia/NZ, Europe all have english dub and subs so you can choose. Asian countries are normally just Japanese language and english subs. The Asian releases are cheaper, but again dont have the dub, i personally hate english voice acting, very cheesy.
