Studio Libeskind's design -- a tower that rises 1776 feet into the New York skyline, with six acres of memorial space and 8 million square feet of office space?
Or will it be...
The design by the International THINK Team? Two 2,100-foot tall metal towers, which includes a building 1700 feet tall.
Either plan will dwarf Malaysia's 1,483-foot Petronas Twin Towers, becoming the tallest building in the world.
