HBO has released another trailer (embedded above) for the upcoming adaptation of George R.R. Martin‘s bestselling A Game of Thrones.

The trailer aired immediately before the season finale of the vampire hit, True Blood–perhaps a sign of the network’s faith in the upcoming series. Release is set for 2011–what do you think?

Earlier this year, we noted how Martin instituted a new policy following the release of the trailer. The io9 blog also linked to a behind-the-scenes video feature, taking a look at the Belfast set.
