My speculation about the outcome of next episode:
I can't wait to see this episode but also dreading it since many characters could die. I don't expect either side to have a decisive victory. If the good guys win and the Night King is destroyed then it will make the rest of the series less suspenseful as there has been a lot of build up for the Night King and the army of dead. If the bad guys win then the next battle will be army of dead vs Cersei's army and the audience will not like either side. I think the latter is more possible given the history of the series. If they want to surprise us then most of the good guys have to survive.
So I expect no decisive victory. The army of the dead will still be strong and keep marching south with at least one zombie Dragon. Some of the good guys will survive and will have to join forces with Cersei with her being the lesser of 2 evils. At least one good Dragon will survive too.
