Was really annoyed at GRRM for that. He put a post up on his not-a-blog saying that there would be a preview at 8:45 before the season opener of True Blood. We sat through 14m30s of True Blood promos to see that twenty second clip that showed almost nothing.
But yeah, we ordered HBO because of it*, so looking forward to seeing how it goes.
