I guess the question then is how will he talk about it? In light of criticisms leveled against TFA he seemed to concede a little and acknowledged the ways it was a copy of ANH, though I don’t see him doing the same for TROS being so messy, it’s not as direct of a point. Maybe one day he’ll say he regrets not going in with a stronger plan for the trilogy from the beginning, or admit the whole dagger quest was lazy overall, maybe he’ll talk about the Kylo footage that never made it to the theatrical version, but there won’t be a tell-all book about it anytime soon.
