Very short, but packed with information and quick shots for the eagle-eyed. Sean Bean as Eddard drawing his sword from a wolf's head scabbard held by Alfie Allen as Theon Greyjoy; Dothraki bloodriders crossing swords at Drogo and Daenerys' wedding; a raven arriving at Winterfell; soldiers bearing the Stark banner riding (probably back from Gared's execution); Robson Webb as Will and Richard Ridings as Gared looking terrified in the Haunted Forest clearing as the Others close in; and a slightly unexciting (but still not finalised) logo.

A considerably clearer and more pause-friendly version of the trailer in Quicktime format linked below.
