I also doubt George would allow a comic to spoil his Sequel Trilogy plans.
George had Sequel plans back then? Huh.
Before the "I said do sequels, because I’ll probably never do sequels”, also the “There will definitely never be Episodes VII-IX. That’s because there isn’t any story, I mean, I never thought of anything!”, and “That was created by the media, not by me.” in response to the question ‘Wasn’t there talk at one time of three trilogies?’ 😉
Taking an unreliable narrator at their word is tough the best of times.
Back to Minch’s ‘Did you think Lucas regret the way Palpatine died?’
I don’t think George did regret it. The toy and merchandise sales for Palpatine weren’t too high around the time of Return Of The Jedi! And the story was for Palpatine done, despite Ian McDiarmid asking George about it a number of times!
