According to a LinkedIn resume of someone who says they're working on the project, the upcoming Sony brawler PlayStation All-Stars Battle Royale, will be coming to the PlayStation Vita.
Originally spotted by The Gaming Liberty, the rumor concerns the resume of Sony sound designer Robert Krekel, which lists "Sound Designer - PlayStation All-Stars Battle Royale (PS3, Vita) as his current project.
As of now that's still not a confirmation. This could still be a simple mistake, but these rumors do tend to end up being correct in the end. So while a resume mistake is certainly possible, right now it seems unlikely. Especially given that Sony would obviously want to support their new console with this fan-service superstar-laden romp.
