Hi Ken. Perhaps you are confusing the transfer from film to digital, versus the transfer from digital to user media. Of course transfering to BD is different than transfering to DVD. Folks here are talking about the earlier step which is transfer from film to digital, and given that it was done in 1080p there is a very good chance that it won't be done again. Else why would GL have done the last transfer in 1080p in the first place? It was done for this very purpose.
Of course it will look better than the DVDs because it won't have been downscaled.
I also would be surprised if they didn't tweak the colors [sic] -- in fact I'll bet that they'll reduce the blue a bit in ESB in post, and that will get a bunch of the apologist brainless sheep beaming that it's a brand new transfer. Haha! That's just a prediction of course... might not happen. But if it does, I'm going to say "told you so." :)
All of the above is irrelevant, however, because it's not going to be the original academy-award winning trilogy that came out in 1977, 1980, and 1983 and changed the world of movies. I'm waiting for that and until then I'll stick with the fan preservations. That much we DO know, and it's enough for me. I'm just not interested in watching early CGI remakes of ground-breaking 1977 special effects.
