Marvel was initially planning to release a boxed set of all of their Phase 1 movies in a special briefcase set that includes a glowing Tesarect cube at the same time as the DVD release for The Avengers. However, shit hit the fan and that isn’t happening so quickly; the release date has been delayed for some unspecified time in spring 2013.
Turns out the Marvel Cinematic Universe: Phase One super epic boxed set won’t be released because a German luggage company called Rimowa GmbH filed a trademark claim at the beginning of August because the briefcase that houses all the DVDs and the Tesarect is apparently a knockoff of one of their products. And apparently it makes them look bad. I don’t quite see how that line of reasoning works out, but whatever. Consequently, Marvel is pulling back all the sets so they can redesign the package for a 2013 release date.
The Avengers DVD will still be released on September 25, 2012 as planned and Marvel will continue work on their Phase 2 films, which include Iron Man 3, Ant-Man, Guardians of the Galaxy and sequels to Thor and Captain America.
No idea what the redesign of the briefcases will look like. In fact, there hasn’t been any official comment on this matter yet, as far as we can tell.
