Without getting into specifics, the Shout set is under licence from both Paramount and WB. Such licences are time-limited and usually print-run limited. My best guess is that there was an exclusivity window with respect to the Paramount films [1-8], and that once that window expired, Paramount was free to issue their own set, which is more of a [as others have indicated] mass market item for the general public than a "box set". I also suspect that part of the higher-than-usual MSRP for the Paramount pack is the inclusion of digital copy.I have never seen two competing sets without one being OOP? Is the Shout set long for this world?
