Do you mean John Knoll ? The guy who sold the idea of the Special Editions to George Lucas ?!
Yes. But that does not mean we won’t see the original version. He no doubt has a lot of respect still for the original film because he was the one also playing that nice extended scene in the deathstar conference room. And talking about Peter Cushings acting being good.
He may realise now you can not beat the real thing…
You’re right, John Knoll is not responsible for the disappearance of the originals.
