I think the wall is coming down.
I think the magic The Night King touching Bran Stark that let The Others/White Walkers and The Wights into the were-wood tree in the North will also help to bring the wall down so that The White Walkers can go south too.
So it will be ironic that a Bran “The Builder” Stark built the wall and a Bran “The Three Eyed Raven” Stark will tear it down.
Also maybe not the whole wall will come down.
I have no prior knowledge. No show notes. This is purely a hunch. Should know the full answer in two hours whether I am right or wrong. I had to put it out there.
