Here's something from

I hadn't heard any LF employee use this angle when the original versions come up, at least it's a further step away from "they don't exist":
I first had the chance to sit down with ILM Digital Artist John Goodson and Visual Effects Supervisor Bill George. They told us a little about the films on the Blu-ray and in particular which of the many variations of the Original Trilogy we would see. “It’s the Special Editions, that’s what George [Lucas] wanted. If you had two films on a disc would have compressed them further. So it’s one film per disc for the maximum resolution,” I asked them if they had a preference and they avoided the question with tact, leaving us in no doubt of their feelings.
