Just to compare, One World Trade Center has 3 million square feet. The ESB has 2.7 million sq ft. A "2.85 million-square-foot tower", and a smaller footprint will make this a monster.
Add now some architectural elements, and there is a good possibility that this could be NYC's new tallest. I'd be nice to get a megatall but I might just be fantasizing at this point. Either way, something very tall is going to rise for sure.
