You do realize all the Theon scenes are from book 5 right? GRRM is already losing content from book 5 into season 3. If they continue sucking in Feast/Dance into Season 4, well GRRM needs to get really busy writing Song and take some time off writing all the other things. I really hope (and expect) most of Feast/Dance will be compressed. It will be really easy to do, we had 200 pages of turtle and wilding armor descriptions in book 5, a single picture will cover all that unneeded description. The actual plot/character progression in book 5 is about 2 episodes worth of content.
