The Japanese release of PS4/Vita Skullgirls is reportedly hitting some last minute turmoil. Ark System Works today released a public statement announcing that the game will be delayed from Jan 28 to March 10, citing "quality improvement" as its reason.

The Japanese release of Skullgirls will feature local voice actors, most of whom are casts from Ark's Blazblue series such as Big Band's voiced by Ragna The Bloodedge's Tomokazu Sugita. Preorders from selected shops will come with additional bonuses such as a Marie tapestry from EBten.
