I would be disappointed to no end if they released what they'd call the "original" versions and there were recomposited shots in it, maybe even more than them not being released at all actually. It may actually make me weep a little. The recompositing for me may be the main (yet far not the only) thing that pisses me off about the SEs. I just can't wait to be able to admire the original FX shots (just as they were created in 77, 80 and 83) in HD and recompositing totally ruins that.
I'm not much of an audiophile, so I wouldn't really mind if all the original mixes weren't included, but I'd of course prefer if they were.
