Spaw, you hit on something that has already been mentioned and what may prevent another skyscraper from being built. Not many companies would rent space on the top floor of another skyscraper at that particular site. Unless they get committment from several high profile companies willing to sign a deal, a skyscraper of WTC proportions won't be in the plan.

It will be something that will be recognizable in the skyline, but I doubt that they will end up with something that tall.
