I kind of wish that they had finished the 3D versions of the OT (with updated effects) and released them by 2017, because then they would have continued as cultural touchstones for a new generation.
Maybe just me but when I was a kid I never cared about the special editions. I honestly didn’t even notice the effects had been updated, only the obvious things like the extra stormtroopers that corner Han, the Wampa, Jedi Rocks, etc. If you show your kids the originals at the right age (i.e. early) they won’t even know they’re old movies.
But in terms of there being a new significant re-release of the OT, there’s probably something to be said for that (and it’s almost certain that if Lucas started with ANH in 2012 he would have made a lot more money than TPM 3D did).
