What's the best online location to get up-to-date info about the plans for Ground Zero?

I’m watching an episode of Penn and Teller’s ‘Bullshit’ entitled “Ground Zero”. The episode is about 4 years old so surely out of date. So it has me curious about the current state of the plans for the site. What is the best website to find out?

Rebuilding Ground Zero has nice photos

I think the pictures on the National 9/11 Memorial website are actually more instructive. Thre’s a construction webcam and an archive ofmonth-by-month photos and construction updates

The official website for 1 World Trade Center (the new name for the former “Freedom Tower”).

Also, the Port Authority website.
