Similar to the 2011/2012 Playstation Vita release of Disgaea 3: Absence of Detention, Nippon Ichi Software confirmed earlier this year that they would be giving the same treatment to Disgaea 4 by porting it over as Disgaea 4 Return.
While we can expect more goodies on this title in the coming days, it has been confirmed in the latest issue of Famitsu that the game will be available on Japanese store shelves from the 30th January 2014. NIS America have yet to confirm any international release plans, but the game still remains available for purchase on the Playstation 3.
