I wasn't thinking that 'Revenge' is the fake out like 'Blue Harvest' but more of a way to differentiate the information flow. They had two titles one which was going to be final and one which was semi-fake. If they wanted to treat trusted sources with more proper information they could have gone with Return, and people they dealt with who they liked less could have been given the 'Revenge' title. It's a 'people in the know' kind of thing, if a reporter back then went up to someone at LFL and asked about Revenge of the Jedi, one storyline could have been dished out. While Return (which was less used) they might trust more. /speculation
