His full response on the current state of the PS Vita version of the game is as follows:
“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.”
It was previously announced that both the PlayStation 4 version and PS Vita version of Skullgirls 2nd Encore would come out this past July. The PS4 version did arrive but, obviously, the PS Vita version is still being waited upon. Now you know why.
