Arc System Works (of Guilty Gear/BlazBlue fame) have announced that they will be cooperating with Lab Zero Games to publish the PS4 and Vita versions of Skullgirls 2nd Encore in Japan. This announcement comes bundled with another, equally-large announcement: Skullgirls 2nd Encore will feature full Japanese voiceover for its overseas next-gen release!
While the full cast hasn't yet been revealed, GamesTalk has divulged that Filia's JP voice actor will be Ayana Taketatsu, well-known for her many roles in both anime and video game voice acting.
It's unknown if territories outside of Japan will eventually have the Japanese dub backported to them, but Lab Zero have stated that such an occurrence is unlikely to happen with the international PS4 release due to licensing costs. Stay tuned for more info on this as it comes in.
Famitsu has a write-up on what players can expect from the Japanese release, and GamesTalk has created a quick n' dirty announcement as well.
Now I wonder what's up with that background...?
