It is very sad, films which are currently being restored and released on BD are commonly scanned at 4k or higher....and the master that was used for the SWBD's was scanned at 2k in the mid 90's.....and theres possibly no chance of a higher scan of the original cells because they won't contain all 'the improvements' that Lucas has given us since then.....but what about Ultra HD currently in development?
For someone who prides himself in pushing for digital over film, you'd think he'd had the foresight that 2k wouldn't be sufficient for long.
