The long awaited sequel to Naughty Dog's 2007 title Uncharted: Drakes Fortune has been announced.  Uncharted 2: Among Thieves once again stars Nathan Drake(complete with half-tuck), who is presumably looking for some sort of treasure in relationship to the voyages of 13th century explorer Marco Polo.  Among Thieves will feature various enhancements from it's predecessor, including a new free form rock climbing mechanic and some Solid Snake-inspired stealth moves.
