the owner might be trying to hold out for more money. it said in the artical that he bought it out from under Campell Soup "Campell Soup is investing $90 million to upgrade its world headquarters, which is located directly behind the Sears Building. City, county, state and the Delaware River Port Authority are contributing $23.5 million to upgrade road and utilities in a 110-acre swath of land.
Campbell Soup had hoped to buy and demolish the building, but was thwarted by the last-minute sale to Zaken. At first, Campbell agreed to work around the building with the expectation that it would be restored. When nothing was done, it offered Zaken $3.025 million. When Zaken refused, Campbell asked the city to take the building through eminent domain."

Something seems wrong here.
