When the show adapts scenes directly from the book they are generally really well done, but the vast majority of their completely original content is on par with True Blood. Occasionally entertaining, but mostly garbage. I don't have much faith that this season is going to go well if they decide to go even further away from the books. I wonder if Brienne's story is also on hiatus for a year? I know the actress was cast for Star Wars. If they cut Stoneheart, already changed Brienne's story drastically from Feast of Crows, and are having Jaime go to Dorne, it's hard to say what they will come up for her to do if she does appear in season 5.
Season 5 shooting underway, Arya appears to already be sporting the cat of the canals look, and a few other pics. http://winteriscoming.net/2014/09/21/game-of-thrones-braavosi-filming-stark-lannister-tyrell/ It would seem Meryn Trant has made his way into Arya's general vicinity which probably isn't gonna end well for him.
