Possibly cost has to do something with it. Assuming News Corp and the rest follow. Its still going to be very expensive, but I have this odd feeling its because of price. Even though they said differences in the floors, that could be modified without changing the whole tower. A redesign sure, but keep the top portion and the rest but focus on the interior.
In Silverstein's case though, he's waited so long, and if the deal goes through, its a win for him, for his dream of finishing the complex before his lifes over, and for the city. I think he will take a chance with it. Given its name, location, this will probably be Ingels biggest challenge yet. Lots of lsd will be needed to come up with something that will beat the current 200 Greenwich design.
If it means getting a tenant and seeing the WTC complex one step closer to completion, I think it beats them going to the West Side. We still have WTC 5, but Tower 2 needs to rise. Been too long. We have assurance that it will be the same height, and its up to whoever designs it, IF the deal goes through, to make it happen. What would be a sacrilege is if this was 700 feet suddenly, but thankfully its not.
Now a nightmare scenario would be if they picked Kaufman or Peter Poon. I would probably move to Madagascar and eat bugs due to the distress that would cause.
