Game of Thrones

I think they'll address it, but not in sync with the book's story line. They already made changes to make Bran's story line more interesting. The surviving Nights Watch traitors and Coldhands meet were suppose to do battle at Crasters. Coldhands leads Bran to the greenseer, so it's a critical character to omit entirely. They also omitted "warging" between Ned Stark's children and their direwolves. Bran is seemingly the only one that can do it so far.
