The ever reliable Chris McFeely of our 2005 Boards has posted an email he recieved. The email is from Maximum Entertainment's Colin Lomax.
As a result of disappointing sales we have decided against continuing with the 'complete set' approach and have instead chosen to release the episodes on single DVD's at a lower price point. Consequently we won't be including any extras. We may revisit the box set approach when the new Spielberg movie is released but not for now.“
