It’s still listed on several websites, but here’s the official word from Maximum Entertainment’s Colin Lomax on the fate of this set
“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.”
So if anyone was holding off on buying the two individual sets in favour of waiting for this, hold yourself back no longer.
