So...

Episode 1 barely gave us anything about book 6, apart from confirming Melisandre being glamoured, but episode 2 implies more, right?

First, confirmation that Euron killed Balon? Maybe a suggestion that he's actually undead, or possibly that's just a sort of impression. Unless it's just something GRRM never confirmed and left it up to the TV show to go with.

Without Victarion, is Yara going to be going on a big quest to Dany, although minus a marriage pact I suppose. Or maybe Theon's going to take that one on. Again, he's not going to be requesting a wife but maybe absolution?

Roose Bolton's death really seemed like a missed opportunity. As I mentioned in the other thread, it felt like he wouldn't have put himself in that position but also I feel like he should really have a vengeance death of sort for his part in the Red Wedding. If Stoneheart is responsible for that it could be why in the show they've had to kill him off differently.
