After a couple of, err, super-teasyGame of Thrones Season 3 teasers (emphasis on the tease), HBO has finally dangled the carrot just enough to have us chomping at the bit for March 31, 2013. The new promo not only discusses the "tremendous reversals of fortune" that occur in book (and Season) 3, it also introduces new, very important characters like "King Beyond the Wall" Mance Rayder (Ciaran Hinds) and "Queen of Thorns" Olenna Tyrell (Diana Rigg).
