Can't see us going for the box look after so much effort went into the rounded look, but I get the gist of what you mean with perforated cladding.

I can't either. I imagine it'll join from the top of the wall to the roof on both ends and perhaps in the corners with the North Stand being left (which is what has been said on Red Vee). As a North Stander I'd be extremely disappointed if all stands were cladded apart from the North. If anything it should be the Away end that is completed last.
