Insomniac Games finally pulled the curtain back on its new Ratchet & Clank project with the reveal of Ratchet & Clank: All 4 One for the Sony PlayStation 3.  The co-op multiplayer title for four players launches in Fall 2011 and features new crazy weapons and playable characters such as Captain Qwark and Dr. Nefarious.  Check out the trailer to see how it all goes down (and find out what's become of Qwark after being stranded in space with the killer beast that is Snowball at the end of A Crack in Time) and get the quote about just what this game entails direct from Insomniac:

Ratchet & Clank: All 4 One is a four-player co-opexperience with huge cinematic-quality battles and tons of cooperative gameplay. While Dr. Nefarious and Captain Qwark are no strangers to the Ratchet & Clank franchise, in All 4 One, you will be able to play as them alongside both Ratchet and Clank. If that wasn’t enough, there will also be an online drop-in, drop-out feature, so you can play together side-by-side or online with up to three other friends.

The co-op angle worries me a little since I seem to have trouble collecting friends for online multiplayer (put down the Xbox 360 controller and turn on your PS3 once in a while, darnit), but more Ratchet & Clank is always a good thing as far as I'm concerned, and being able to play as Dr. Nefarious is just the icing on the cake.  A year seems like a long time to wait, but I bet there's plenty more to this game that we haven't seen yet.
