Please don’t judge me when I say that I hope the Revisited versions of the OT won’t contradict the official versions of the PT. Then again, since the OT is so sacred to many, most of the changes made to them are aesthetic, and not story-related.
Some of Adywan’s changes to RotJ may depend on what he can change in the PT. I’m still sure they’ll fit better than how much the PT already contradicts the OT.
