The new glass is approved and going to be similar mirror glass as in the first 30 floors of the building. The problem was that the original manufacturer has gone out of business since then, so the new glass won't be exactly the same tone as the new one. It should be a very close match and I hope the end result is completely unnoticable, but we don't know that yet.
I will post photos in few weeks once they are working on our floor.
