Ratchet & Clank developers are hard at work on a new exclusive PlayStation 3 title, the developer confirms this afternoon.

The Californian game studio revealed that work was progressing apace on the new, unnamed game, while celebrating their role as one of California's top companies to work for.

Of course Insomniac still won't be drawn on the identity of their new game, although chit-chat suggests that one new title will be a sequel to the hit title Quest for Booty.

Given that Insomniac are also the team behind hit series Resistance, it is also possible that their new project might be related to this altogether grittier franchise. We're hopeful of official word on whatever they're planning soon.
