Double Eleven is converting a PlayStation 3 exclusive title for PS Vita and PS4, although we've no idea what game it is.
Speaking on twitter, Double Eleven boss Lee Hutchison said, "Our next title sees another PS3 title being adapted & improved for PS Vita. Starting at 3fps its an optimisation mission to get up to a solid 30 FPS."
Later he added that "The PS4 version needs optimisation too, saying that "It's all about core speed and adapting an existing code to ultilise multi-cores better."
He was asked if this would be coming to other platforms but revealed that it is a PS Exclusive, before revealing that the announce should be within the next month.
What game could this relate to? You're guess is as good as ours (Journey, Puppeteer?).
Double Eleven previously worked alongside Media Molecule on LittleBigPlanet for PS Vita, as well as DLC for the PS3 version.
