For those who have little space and simply have to double-dip on Blade Runner's another BD release (this time it's the 30th Anniversary one), there's some good news. You don't have to pick up the huge box, you can get a 3-disc digibook instead ;) It hits the streets in October. At the moment there is no link available for the purchase of the digibook, but you can go ahead and secure your copy of the badass box here: Amazon.com
Looks lovely, may I add.
EDIT: pre-order link for the digibook seems to be already available afterall! Amazon.com; $24.49
