Through financial reports, Siliconera noticed that Atlus only expected to sell 75,000 copies of the game in North America. By the end of February 2010, however, Atlus has shipped a whopping 280,000 copies of the game to retailers.
nope If a sequel is in the works, Joystiq notes that Sony might step in and publish the game in the United States themselves, which would be an unfortunate loss for Atlus.
As for Europe, it appears that Namco Bandai could be publishing the game in Germany and other territories, as a rating has been spotted. (Thanks, Stefan1904)
