However, I think there is a clear difference between improved digital compositing and the other SE changes. No-one wanted garbage mattes to be visible in '77 and removing them does not constitute a change in the same way the other SE additions do. It would just be using modern technology to acheive the effect that really was originally intended. If the '06 editions are original in every other way but have better compositing, I will be perfectly happy.
