The European (R2) Collectors edition (5-disc)

Update
I’ve been in contact with Warner Bros. in Sweden asking about the Collectors edition (5-disc) of Blade Runner: The Final Cut and I where told (This is the Swedish release and Im 99% sure that it goes for the rest of europe too) that it will include the same items as the American (R1) version but the packaging will be different.
It will not be packaged in the briefcase. Other than that it is the same stuff on all the discs and it will include all the extras as the signed letter from Ridley Scott and the collectibles.
Discshop, The largest Swedish on-line store has the 5-disc collectors edition and the 2-disc version of Blade Runner: The Final Cut available for pre-order, preliminary releasedate is set to the 5’th of december 2007
