Watching the preview for next week, I noticed there's a very quick shot of the survivors gathered in front of Winterfell with some of the major characters carrying torches towards what appear to be large funeral pyres.
I took a screen grab and labelled the people I could recognize. I know some people avoid the promos at all costs, so I've put it in tags. It doesn't really spoil anything if you've already watched this week's episode.
Spoiler!
If you open this in a new window, it will display at the full 1080p resolution.
Notably absent are Brienne, Jaime, and Pod. Also, I don't see Gilly and Little Sam (but she does appear later in the promo).
This confirms a few survivors that people were wondering about.
