The Spartacus War of the Damned U.S. dvd/blu ray release is September 3 2013.
What a difference from the UK release eh? September has always been normal timing. All the Spartacus seasons were released in September in the U.S. Sometimes I see people complaining about the long wait, but consider this: if you want good quality and lots of content with extras and bonus features, it takes a proper amount of time to make it the very best it could possibly be!
