While we await David O. Russell's expansion of the Uncharted universe no one asked for, Naughty Dog recently announced a sequel to be released in 2011, tentatively titled Uncharted 3: Drake's Deceit.  The game will feature Nathan Drake and partner Sully on a hunt for a lost city, featuring locales in the Arabian Peninsula and Rub' al Khali Desert. Details on the game remain scant for now, though Naughty Dog does promise more multiplayer offerings and the ability to fight multiple enemies at once. 

Expect Uncharted 3 to drop in late 2011. In the meantime, enjoy this first teaser trailer.
