I don't mean to be so pesemistic, but I personally beleive it won't ever, could I be wrong? sure. I know the old WTC took a long time, But there is no way they are ready to build this tower in april, or next year. There are too many blockers and problems the site has already. If it happens to be built than that's great but I'm going to count on the site being sold to different developers and them doing whatever the hell the want with it. So I think it's safe to say there will be no more tower 2 either.
