I hope the smaller of the two new swords is for Tyrion. With Jamie sticking with the Kings Guard, Tywin needs an heir to Casterly Rock, right? Whoever it goes to, I want both swords reunited with the Starks one day.
The Doom of Valyria... Sounds bad. Is Dany is anywhere around Valyria? Besides making great steel and some Doom-y event, do we know anything else about this place? It comes up frequently enough that it probably ties in somehow. Perhaps Dany and Co. will swing through on their "attack every city on the continent tour". I'm a little restless with this storyline, apparently, but this next city, Mereen (?) might be a notch up on the evil meter. Could be fun.
The Fool and Sansa sequence, for me, felt like it put her on the path towards becoming something more than a victim. Perhaps we see her start playing the game now. Everyone would surely underestimate her to an extreme degree, leaving ample opportunity to strike one for the good guys.
Lastly, I wonder if the Wildlings and Nights Watch can form an alliance with the white walkers coming. Jon's Dances with Wolves experience might have given him the insight to question why, exactly, they are about to slaughter each other. They seem like two feuding siblings who have been fighting so long they may have forgotten why they even started. I guess cannibals are kinda bad but Ygritte and the gang seem like decent folks.
