Nothing official yet, but you probably wont have to import Atelier Rorona. During E3 we heard Gust’s first PlayStation 3 game is being looked at.
I wouldn’t expect Atelier Rorona to come out overseas this year, though. Between finishing Atelier Rorona and tweaking Mana Khemia 2 for English text Gust is pretty busy. While we’re searching for more information, watch this trailer and meet the characters.
