Because it's Atlus, the only company to ever region lock a PS3 game.
Yeah, and it only did it for one game, and it got a lot of crap for it. It was also an Atlus developed game, not just published. I doubt Atlus will region lock this game. --- My Ultimate Dormammu Guide: http://tinyurl.com/6mr4lhv My UMvC3 Team Building Guide: http://tinyurl.com/8x865ra

Update: I PMed Jason and asked him about getting an update on the game, and he had this to say:
Hey! Well it was a very early (Japanese) build, so it's really hard to give conclusive opinions. It basically felt like co-op Odin Sphere. Side-scrolling beat-em-up, etc. And yeah, it still exists!
I'll have a few more thoughts/details in a big piece on Atlus that's going up on Kotaku within the next few weeks.
Thanks for posting this. This is news, I'm surprised that no one else in the topic commented about this. --- Please support the localization of the Senran Kagura games: http://www.facebook.com/pages/Senran-International-Academy/269180386535793
