This trailer was just released today, and shows the most in-depth footage of the upcoming season yet. A lot more emphasis on Robb, as he is to become a major player in the main arc. The upcoming season looks fantastic. The production team has really outdone themselves with setting. And it seems like the mainstream success of the show has enabled the producers to expand their budget to get some of those exotic locales. And hopefully get some large-scale battles in, since they seemed to avoid those in season 1.
I really can't wait.
In the meantime, I'll probably re-watch season 1... Or at least the crown of gold scene.
