After being rumored last week, we can now confirm that PlayStation All-Stars: Battle Royale will indeed see a release on PS Vita.
The confirmation comes from the online CV of a sound designer at Sony Computer Entertainment America.
The employee lists the game for release on PlayStation 3 (announced) and PS Vita (unannounced).
What would be cool is if the Vita/PS3 versions included cross-platform play.
E3 2012 is just around the bend.
