There have been signals out there that Sucker Punch is currently working on a new project, and a new career opportunity ad seeking a Narrative designer recently published by the developer serves at the clincher.

Sucker Punch is looking for a temporary Narrative Writer to help create engaging and compelling narrative content for our upcoming project. Daily tasks will include story development, game dialogue and general narrative contribution. The ideal candidate will have previous success as a game writer or screenwriter, outstanding communication skills, a good understanding of story and game structure, experience in a writers' room setting, and an absolute passion to tell great stories in various cinematic mediums.

Even more interestingly, we learn that the game will be open world:

Collaborate with content designers, writers and creative staff in creating original narrative content and believable characters for an open world game

Experience in playing open world games.

Considering that open world games are Sucker Punch's bread and butter, it's really not much of a surprise that they're still betting on their winning horse for their new project.

Interestingly, they're also continuing with the trend set by inFAMOUS: Second Son and stressing on diversity within the cast:

Collaborate with writers, designers and cinematic artists to write and edit compelling and unique dialogue for a diverse cast of characters.

At the moment nothing else is know about the new game. It could be another stand-alone expansion like inFAMOUS: First Light, a completely new chapter of the inFAMOUS series, or something else entirely.

Sucker Punch will be present at PlayStation Experience, so we might hear something there.
