Devil Survivor 2: Break Record was originally scheduled for release in Japan on July 20th, 2013. The reasoning given for the delay is that the quality of the game is not up to the standard desired by ATLUS, which in turn is resulting in more work needing to be done to polish up the game before its release presumably around October 2013 when Autumn hits.
This is of course disappointing news for both the Japanese and Western gamers as it means that the eventual localization of the game will also be pushed back even further for us. We will keep you updated as more information on this news comes to light.
