Wall Street Journal: The final tower planned at the World Trade Center redevelopment could be dramatically altered under a proposal being discussed by 21st Century Fox and News Corp., which are said to be considering a move to the site. The media companies and developer Larry Silverstein have brought in avant-garde Danish architect Bjarke Ingels to redesign 2 World Trade Center in the event of a move. A deal is far from certain, as the companies are also considering a renewal of space at their midtown headquarters.
