Hi Gordy. I went to Amazon UK and, after seeing the picture of the box, wish they'd done that in the US (along with 10 single discs). And the 30th Anniversary edition looks even better with special packaging and a copy of the companion book that is out of print -- but I'm sure the US will never get that!
Also, you must get two releases to get the full New York documentary -- the 7 DVD box set, and Episode 8 (New York: The Center Of The World, which chronicles the rise and fall of the World Trade Center) which is sold as a separate single disc. The original 7-DVD set was released in 2001, the 8th episode just last month (the original series doesn't specifically refer to the Twin Towers at all, so the 8th episode does make the documentary feel more "complete" -- and after 9/11, any history of New York wouldn't really seem right without a discussion of the rise and fall of the towers).
