Preview at WWDC likely in June, followed by September launch.
Apple Campus 2 Drone Video Shows Progress on Main Building With New Solar Panels, Windows
Over the course of the last month, Apple has continued adding more massive curved glass windows to the main ring-shaped building. Because the windows are so large, it's taking Apple several months to get them all in place. Additional window shades and solar panels are also going up, and it looks like it'll be a few months more before work on the main building wraps up.
Both the auditorium and the two massive parking garages are nearing completion, and solar panel installation is largely finished on the roof of the parking structures. The fitness center is still being worked on, and the Tantau research buildings are looking more polished.
Parking tunnels also look to be nearly done, and the two major dirt piles on site, which will be used for landscaping, are currently untouched.
Drone pilot Matthew Roberts has also shared a June campus update video, offering a closer look at the progress made on the roof of the main ring-shaped building and a wider view of the parking structures and auditorium. There's also a close look at some new buildings being constructed on Tantau Avenue, which will be used for research and development purposes.
Last month, Apple began taking down the green privacy fence surrounding the entire campus, replacing it with a shorter chain-link fence. The gates are often left open as well, allowing passersby to get a close-up look at the campus and the ongoing construction.
Apple plans to complete work on Apple Campus 2 at the end of 2016, with employees set to start occupying the facility at the beginning of 2017.
