Skullgirls was a hit on PlayStation 3 and Xbox 360, and in 2014 Lab Zero Games announced it would be coming to both PlayStation 4 and PlayStation Vita. While the PlayStation 4 version released this past July, there has been no date given for the PlayStation Vita version. During a Reddit AMA designer earlfriend gave the following explanation,
Skullgirls 2nd Encore for Vita is still undergoing optimization, and there are a number of bugs to take care of that, while somewhat small, we feel are unacceptable to ship with. We want it to be on par with other fighting game releases for that platform, and it’s unfortunately not there yet. We had originally projected it would be ready to ship a few weeks after the PS4 version’s release, but we ran into walls trying to bring optimization up to par, and grossly underestimated how much work that would require. This moved us into a timeframe where we had to start implementing features for the upcoming release of the Japanese version, which has further contributed to the delay.
