The news comes courtesy of NeoGAF:
“There’s a pre-screening event for the first episode of the Devil Survivor 2 anime in Japan right now. They promised a special announcement as well, and fans at the event are reporting that they have announced Devil Survivor 2 Break Code for the 3DS. The new release will contain new story and character content, and it’s due for release in Summer 2013 in Japan.
The game will be featured in a future issue of Famitsu this month, but I’m not sure if the “March 28″ issue refers to the street date or the cover date. Either way it’ll be 2-3 weeks from now.”
So it looks like Devil Survivor 2 is going to receive the same treatment as the original Devil Survivor, which also saw a highly rated 3DS remake.
