Nippon Ichi Software is hard at work. Not only did they confirm Disgaea 3: Return to be in development for PlayStation Vita; the Japanese RPG developer is also teasing four more titles.

Speaking as part of a publisher interview in the latest issue of Dengeki PlayStation, NIS provided bits and pieces of details regarding the upcoming mystery projects.

Game 1: An action RPG with full polygon visuals from the team that developed PSP’s Prinny: Can I Really Be the Hero? and its sequel. In development for an unspecified platform, we should get our first look at this title in about a month.

Game 2: A brand new title from the Disgaea team, said to have the visual quality of Disgaea 4‘s illustrations. The staff is applying the knowledge its gained in networking and other areas from developing Disgaea 4. A famous illustrator is doing character designs. A platform was not specified.

Game 3: A new title from System Plasma, developers of Classic Dungeon. A platform was not specified.

Game 4: A Japanese release of a popular overseas 3DS game.

Nippon Ichi also said it would like to make a sequel to PSP’s Criminal Girls for PlayStation Vita. Though, this won’t happen at the moment, as they would not create a sequel without Kazuya Niinou.

Thanks, Andriasang.
