While the December 29 home video release of District 9 will disseminate the demo more than a month after the God of War Collection, it seems as though it may have some exclusive content. According to Sony's blog post, completing the demo on the Blu-ray movie disc will unlock a God of War 3 making-of video that hasn't been confirmed to be included in the God of War Collection. We've sent a query to Sony to find out whether or not the video will be included in the God of War Collection.
