I think some of the bad news may be that FX Producer Julia Frey, the person who was tweeting from the location shoots, is not returning for the full season. Also, Robert Stromberg is unlikely to be back due to his recent success with Avatar and Alice in Wonderland has left him highly in demand for big-budget filmwork.
A piece of good news is that Gemma Jackson, award-winning production designer, is returning to resume those duties after having done so for the pilot. She had not been contracted beyond the pilot. She has now signed on for the series.
