I have..a theory.
It really does look like that the walls in-front of the Link Chairs, are full on walls. And not screens.
I am believing, for the time being; that the Walls in-front of the Link chairs, will basically do the same thing in a sense to how the Kuka Arm in Gringotts handled for the finale, pulling out the wall, as the Link chairs physically move to Banshee's, like what was seen a few months ago..
This, is what I am now believing to be the case; as this to me, seems very much that it would most likely happen; and that I am not going to be surprised, if I am wrong.
