I don't think things would change too much. We all sort of ended up here because we didn't fit in with other parts of the fandom. The people who prefer the SE's, and hiss at anyone who likes the OOT, aren't likely to change their tune. Some of them are probably already putting an mental footnote on the sequel that reads "Not By George".

The new films will change the fandom map as much or more than the prequels did.

We should send George a nice note someday, thanking him for unintentionally bringing all of us together, and inspiring the first fan edits. :)
