Well I assumed since the arcade release was international, the console release would be as well.
but who knows. With the 30 hour storyline needing to be translated and redubbed for the US release, it may take longer.
Basically there just isn't enough information to say either or at the moment.
and at the end of the day if you really want the game, PS3 bluray is region free and the online is international. So if you don't care about the story mode importing is always an option.
I'm about 90% sure that it'll get an international release though
