It will happen. Donner is quite excited about it, even if he doesn't want to go into the editing booth himself. He's kinda right about it too ... let somebody who is truly passionate about the material do the re-cut according to his notes, and it'll be done with such meticulous care, that it'll be even better than if he did it himself.
I think this is beautiful. It shows the potential of fan edits to change the landscape of the distributors. This is in DIRECT response to the RIC. Somebody at Warner is starting to get it: Give them what they want and actually make the money, or watch some fan do it for free.
I'll be buying this expensive set on opening day, no questions. I haven't bought Batman yet and have no immediate plans to do so. But this film series ... I'm gettin' the whole thing and replacing the old set without hesitation.
