Thoughts for Season 6:
I sure hope that if Sansa survives the fall, her legs are not broken or anything. I would hate to watch Ramsay walk painfully slow towards her, with that stupid grin on his face if she had broken legs. If she does escape, I suspect she will return to the Vale and try to get Baelish to kill the Boltons.
I would really like to get a glimpse into how Rickon is progressing as a character, and maybe they will explore that storyline since he is, IMO quite important to the northern storyline since he is the rightful heir to Winterfell, now that Bran is beyond the wall.
I sure hope Doran is a man of his word, and does not believe in 3rd chances!
I found it ironic that after 5 seasons Dany is once again at square one with the Dothraki. Hopefully she somehow convinces them to join her in Meereen, because it would be very anti-climatic for her to be killed now.
We should be reintroduced to Bran after a season off and it will be interesting to see the extent of which he has mastered his powers.
After failing to progress much in Season 5, Arya has a lot of work left to do. Now that she is blind I am not really sure what they are going to do to keep that storyline afloat.
Any other thoughts?
