The PlayStation Vita has a lot of great titles in development, and should have one of the best launch line-ups in gaming history. You might be able to add one more possible game to that strong line-up as Yahoo Japan have listed Disgaea 3: Return as a launch title for the PlayStation Vita.
The article goes on to list several newly announced games such as Ultimate Marvel vs. Capcom 3 and Digimon World Re: Digitze, but Disgaea 3 leaps out above the rest. This could be a port of the PlayStation 3 version of the game, or it could be some kind of spin off. The article has since been edited to exclude the Nippon Ichi Software title, so we will have to wait and see if there was any truth to it.
The original bit from Yahoo Japan can be found below for anyone who can read the language.
