The entire clip runs for 54 seconds and shows a dramatic meeting of ice and fire on the map table in Dragonstone. I noticed that in the teaser, just after the wolf statue gets frosted, the scene then shows a carved dragon on the right of the table but on the left of the screen behind the table looks like someone is sat in front of the fireplace. It might be a blurry easter egg or it could also be only a trick of light caused by a reflection.The clip of the wolf statue frosting over as ice moves across the table, heading South, could mean Winterfell is caught in ominous Winter. As ice moves across the map, heading towards the Riverlands, statues of other houses get caught too. It could be the wrong angle but ice moves down across the Iron Islands on the table.
 South of the table, fire moves north across the map. The lion of House Lannister is engulfed in flames. The forces of ice and fire meet on the map at the Twins. Right there where both ice and fire meet, is a creation of obsidian. This hints that a new Wall could be made there in the Riverlands. Winterfell is going to fall (major clue in the name), the Lannisters will be at war against the northerners, and not fighting with them. Other houses present on the map represented by their sigils are pawns. The clearest houses are Stark, Lannister and Targaryen. Most of all, the teaser trailer is showing that there's going to be a massive war. This will be most epic.
