Something we have to remember, though, is that even since the Depp/Burton DS has been in play, it's never been a given that the restoration was going to be allowed and released. The truth is that WB has been dragging its feet on poor Darren all along. And who can forget how not all that long ago they'd announced with great fanfare that the two films were going to come out as a set, also with no extras whatsoever. Sure, they eventually backtracked on the idea then, but that really appears to have been their inclination all along and the only thing new now is that they finally seem to be following through on doing it.
Also, we probably shouldn't confuse the film and video divisions because they're separate entities at WB and they operate independently. The Depp/Burton film could have been a huge success and spawned who knows what and the video division could have still made this same decision. Apparently as Darren says, they believe they've already put in enough money with the HD transfers they already have. And its certainly been a case that all along they haven't believed that there's a big DVD/Blu-ray market for either hoDS or NoDS, so it's not really surprising that they don't believe that putting more money into them will reap any greater profit when their apparent myopia causes them to see the potential market as a finite one regardless of what they may do. We could certainly argue and I'm sure it has been argued that a restored NoDS is likely to sell much better than a non-restored NoDS might. But apparently they've closed both their minds and their pocketbooks to that possibility.
