@Akarou: The hi-def version can be better quality to a certain degree. Luckily, film is actually "higher res" than what it was originally output to for viewing back in the 80s (theater film projectors and VHS). They can go back, get the master transfer and the quality will be better than anything we've yet to see. Not quite as clear as a new HD movie though. In terms of quality, I'd say it sits somewhere between SD and HD to put it in some kind of perspective. They can also remaster frame by frame to fix any imperfections like scratches or dust on the film. I'm confident the Blu-Ray version will be, by far, the best version ever released. However, in some cases in HD media, they have been known to release a bad transfer.. hopefully that's not the case.
