NIS America has dated Danganronpa Another Episode:

NIS America is happy to announce that there is a new trailer and screenshots for Danganronpa Another Episode: Ultra Despair Girls, which will be released in North America on September 1 and Europe on September 4 on the PlayStation®Vita as both a physical and digital release. Unlike the first two games, in this action adventure title players will take on the role of two heroines, Komaru Naegi and Toko Fukawa, as they are thrust into a despair-ridden Towa City with one goal–escape.

This new batch of screenshots show the beginning of Komaru Naegi and Toko Fukawa’s escape out of Towa City and introduces basic gameplay elements while the trailer welcomes you to despair.
