...I know that there are many consumers who would like this. However, we are developing the game with PlayStation 4 specs, so to be honest, it's impossible to port the game to the PlayStation Vita. Porting the game without erasing a lot of features and cutting down the amount of assets would be very difficult, and of course, we do not wish to do that. I think there are people waiting for a "Return" version with all of the contents [and DLC] included, but I'm sorry, that will not happen this time. (laughs) If we were to port the game to a portable system, fans would probably have to wait for the next portable system after the Vita, but I haven't heard anything about this [system], so that would be far in the future. Disgaea 5 will have Remote Play. Do not wait for a PS Vita port, and please, play the PlayStation 4 version.

No biggie. As long as we get the game.
