My prediction;
(Also worth noting, that this is purely speculation on my part, and I haven’t seen/heard any spoilers about the remainder of the season whatsoever)
Winterfell, will fall. A significant number of regulars will be killed off in next weeks battle.
As already mentioned above by SAM, I can see Dany turning moody & causing grief, possibly leading to a significant death of one of the regular faces next week.
The remaining bunch at Winterfell will retreat to the Iron Islands, whilst the Night King’s mob carry on down to Kings Landing.
At the iron islands, something will happen, that will reveal John Snow to be Azor Ahai. At this point, the remaining ragtag bunch of survivors will hot tail it down South.
Meanwhile in Kings Landing, Cersei’s army, and the Gold Company will subsequently get smashed by the dead army. Just before it’s complete annihilation, the Winterfell survivors, lead by Azor Ahai, will appear in Kings Landing, for the final showdown, in which The Knight King will be defeated.
Not sure how it’ll finish, with regards to who sits on the Iron Throne, but it wouldn’t surprise me if the Seven kingdoms were disbanded, and each to be ruled independently.
I still think Bran has a larger part to play, although I’m not sure what yet. I don’t necessarily believe the theory that him and The Knight King are one and the same.
Same goes for Varys, who’s been suspiciously quiet this season.
