Well, based on the latest diagrams of the cantilever tower, I think it is safe to say that it will be at least 1435 ft, and not 1423 ft (unless I am missing something)
I still think this will end up being between 1450 and 1500 with the cantilever, along with a substantial redesign. Steinway has upped the ante too much to be ignored. If Barnett stays with the current massing/render and the earlier 1423 ft height, this thing is going to be an also-ran and totally outclassed architecturally, particularly if steinway pushes up to 1400 ft.
