Jump SQ magazine will give more details this week but it is confirmed!

 'The November issue of Jump Square Magazine that goes on sale in Japan next week will formally announce the development of an Ao no Exorcist (Blue Exorcist) motion picture. The TV series has been simulcasting online, and Aniplex USA will begin distributing the TV series on American DVD next month.'

 If it's in the works already, it could be out by next year! :)

The series by Kazue Kato has exploded with popularity and success!
