Yeah, the majority of panels will be removed more or less at the same time as new installation. But those being removed now seem to be for the setup of whatever equipment is needed to do the recladding. I imagine there will be a repeat of the current panel removal pattern at least once on each side of the building.

I don't think the renders actually show fins, but rather a bit of an optical illusion caused at the junction of white and bronze glass. If anything it looks like the white glazing will extend a bit beyond the current corners, if that makes any sense.
