This should be an action packed episode, and I'll likely be among many if it's missing one of the key scenes. There's so much going on that I wonder how on earth we're going to see it all, even in the longest episode of the show to date.
I agree with Martin himself who would like to see more episodes, even up to 13. Perhaps next season, when (I really hope!) the producers will cram both books 4 and 5 into a single season? I enjoy the pacing of the show (for the most part), and I'm really happy book 3 was split into two seasons. Aside from having to wait another year to see a certain rotten little brat get his death, it was a great choice. But then with books 4 and 5 dragging so much, do we want to see them split? I can't think of any event before the very end of book 5 that would give a sufficient cliff-hanger.
I don't know what else to talk about. We all know what we hope is coming, and we all know it should be a very talked-about episode. I'm going to miss our many favorite characters who won't make it to next season.
