The third season of Game of Thrones has been teased heavily, and a new trailer gives us what we really want: footage from the new episodes. If you've read the novels — Season 3 is based on A Storm of Swords, third in the series — you probably have a fair idea of what's coming, but the trailer is a veritable cornucopia of dragons, ice storms, flaming sword fights, and more of the conflict that erupted last season. As we near the March 31st season premiere, another storm is brewing for HBO, which will see its success from cable-only offerings (subscribers can use HBO Go, but there's no online-only payment plan) weighed against heavy Game of Thrones piracy.
