But that’s not all. HBO is also readying the release of Thrones fourth season trailer. The full trailer will be out Sunday night right before the premiere of hot new drama True Detective, but you might not have to wait that long to see at least some of it. That sounds cryptic, but we’ll have details this weekend. The trailer is described as the “first extended look at the new season and features new characters and episodic footage” (and we hear it’s amazing).
