In an interview with Siliconera, Nippon Ichi Software president Souhei Niikawa explained why there aren’t currently any plans to release Disgaea 5 on the Vita;
“As of right now, we don’t have any plans of doing a simultaneous release on console. If we do a simultaneous release on console and handhelds, some of the things that are unique to the handheld version, for example the traveling feature in Disgaea 3: Absence of Detention, the game would only sell on handhelds which would be bad for us.
From our standpoint, since portable devices aren’t really doing well outside of Japan. It’s better for us to release the game on console first because consoles do well in and outside of Japan and then go from there.
If we were just thinking about Japan we could probably just release all of our games on handheld devices, but we we want our fans outside of Japan to enjoy the games as well, which is why we want to release the games on consoles.”
During the interview Niikawa-san was also asked why he decided to port Criminal Girls on to the Vita, his answer is somewhat silly one;
“In Japan, there were hardcore fans who wanted a continuation of the story. I want to continue it on as a series and keep building it. Our first process in building it up is building it on Vita and I wanted to touch the girls on Vita. [laughs]”
