I doubt that we're going to get anything major in episode ten. As for season four, I've been thinking a bit about what we'll probably see. I think we'll certainly see the rest of the ASOS material, as well some of AFFC, and probably ADWD.
I expect that if we are going to see the Iron Islands storylines, we'll get a lot of that in season four, as Balon is supposed to die around the same time as Robb and Joffrey. I doubt that Dorne will appear at all, unless the trial happens much earlier in the season than I would expect. I could see them ending things in King's Landing with the aftermath of Tywin's death and Tyrion's escape. I could see Tyrion and Arya both arriving in the Free Cities by the end of the season.
