If Blade Runner just put out the final cut it would make a ton of money. Thats all they planne to do, initially. The only reason BR got the royal treatment was because BR is Scott's home video manager and Final Cut producer Charlie DeLazaurika's favorite film. So he went the extra mile because he's BR's biggest fan. It would be like if you or me worked for Lucasfilm and were in charge of releasing the OT--we'd give it the same treatment DeLazaurika gave Blade Runner.

But neither the royal OOT or the royal BR is necessary. Blade Runner happened because someone high up wanted it to. And thats what we need. That was how the 2006 release happened--Jim Ward wanted it to.

EDIT

Also, BR happened because Ridley Scott is not a dickhead.
