I still fail to understand how/why it should be expensive. To release a HD scan of the OUT, you need
- good looking prints - they have them
- a HD film scanner - they have them
- a person who can scan film - they have them
- a person who is able to take HD files and author a BD out of them - they PROBABLY have these persons
- designers (menus, covers, etc)
- marketing team - they have them
So sorry, what costs? They have the people, they have the equipment and they have the prints, and I'm pretty sure such a release would be considered "good enough" for most of us
