Insomniac games finally took the wraps off two of the three games they are working on today as they announced
Rachet & Clank: All 4 One and
Resistance:Fall of Man 3.
Details are scarce right now but
Rachet & Clank: All 4 One will feature four player co-op and be available in Fall 2011 while
Resistance 3 will be available sometime in 2011. There were some rumors that we could see R3 in early 2011 but we haven't seen anything official on that yet.
Update (John) - Added Ratchet trailer and the Resistance teaser
