There was an interview that I think was posted here on TIS a couple months ago where Grace was talking about the NYE shows and how she was alreading thinking about the movie theme for this year.  Wish I could find it.  Seems like they love doing that show ... can't imagine them not doing it somewhere in home territory.  But they are deserving of a good long rest ... honestly doubt that will stop them, though, unless there are serious issues interfering.  Guessing they're just holding off on the announcement so as not to detract focus away from Flynn show.
