It'll be interesting. I think the black & white releases look better than the scanned releases that were issued during the retro event. The latest Saga of the Swamp Thing releases have a few odd book the feature white boarders and clean line work with what appears to be the old coloring with the "dots". Not sure correct terminology but they don't look the good. I haven't decided whether they are better or worse than pure black and white. I bet it's less noticeable on low res screens.

Anyway, I think DC is already moving in this direction. The pre-new 52 collections that were cancelled are all available online. If (and it's a big if) you are open to digital all they are all available on demand.
