At a recent sneak peek screening of the Devil Survivor 2 anime, it was announced that Atlus is working on a 3DS remake of the game called Devil Survivor 2: Break Code. Not much to really say about it at this point, other than I would be surprised if the upgrade isn't much like the 3DS remake of the first Devil Survivor.
(Forgive the typo in the new wiki page title. That was my bad. :P)
