According to GameFaqs there is a DS game in the making slated for release on March 15th. Wasn't able to find that much more stuff on it but I hope as time passes we'll find out more about it. Whether or not I get it depends on what people say about it because a)Import games are more expensive and b) even though I know Japanese I don't know enough to play a game like it's in English. Oh yeah before I forget the title is Kami no Shitotachi which means God's Apostles.
EDIT: Kaze, please don't move this to Game Talk. Most of the people here don't go there that often and vice versa.
