Sucker Punch Productions apparently have an unannounced title in the pipeline and it's neither the electrifying inFamous or sneaky Sly Cooper series. It's an entirely brand new IP.
A Sucker Punch rep had told PSNow! at an event in Madrid last night that they have a brand spankin' new Sony exclusive in the works. Unfortunately, it's said that the game will not see the light of day at E3 this year.
The article has since been edited by the request of Sony.
Sucker Punch's inFamous 2 is set for release on June 7, introducing Sony's Play.Create.Share. core values to the game with custom user-made missions that can be shared across PSN.
