Just prior to spilling the beans on Resistance 3, Insomniac announced they have a new four-player co-op Ratchet & Clank title in development.

The new game, Ratchet & Clank: All 4 One, will feature drop-in/drop-out co-op, where you'll play as Ratchet, Clank, Qwark and even Nefarious. The game's being developed by Insomniac's new North Carolina studio.

The trailer's pretty brilliant to be honest. It's due at the end of next year.
