Apple's yearly developer conference should see iOS 8, OS X 10.10, and likely some hardware.
Apple to Upgrade Fifth Avenue Store Plaza, Temporarily Remove Iconic Glass Cube
Workers reportedly appeared on site last night and began fencing off areas around the store to begin work on the project.
Building permits issued on June 13th state the work will also include removing protective bollards, installing new pavers around the cube's perimeter, and removing and reinstalling surrounding water drains. According to the permits, the work could be finished by early November.It is unclear whether Apple will be replacing the glass panels of the cube or making other changes to the structure, or simply temporarily removing the cube to facilitate other drainage and paver work on the plaza.
Apple's Fifth Avenue store opened in mid-2006 as the gleaming flagship of the chain, operating 24 hours a day. Despite the company having opened a number of significantly larger flagship stores around the world in the following years, the Fifth Avenue store has maintained its position as one of the busiest and most-visited stores in the company's retail chain.
Update: ifoAppleStore has added a couple of photos of the gray plywood barriers around the plaza.
