Saw a link to this Taiwanese blog (in traditional Chinese): http://www.mobile01.com/topicdetail.php?f=248&t=4525712&p=1 The blogger received his 200-500mm/f5.6 on September 5. There are a lot of questions back and forth. So far the blogger is happy with the lens. In the US, Nikon is scheduled to start shipping on September 17, which is 10 days from now. So hopefully there won't be any delay.
