I just rewatched Brans vision from ep2 and realized the show is now spoiling the book. At 3:18 the shadow of a dragon flies over Kings Landing from a POV angle but more important the scene is cut between Brans paralyzing fall. Unless that's a red herring and not a vision of the future, it confirms that Bran will warg into one of the dragons.
3:13 shows snow on the throne, just like Dannys vision. Snow on the throne could mean many things, Snow is a common last name and could easily apply to Ramsay Snow but more then likely it symbolizes Jon Snow sits on the throne at the end.

this confirms Jon Snow is a Targaryen and the reason Danny doesn't take the throne over him is she dies or never makes it to Kings Landing.
3:16 shows a white walker looking into broken shards of ice. This to me confirms that the Horn of Winter has the power to destroy the wall and will be used.
