I can understand having the OUT as one canon and the SE/Blu-Ray versions as another (granted that Hayden reprises his role as Anakin in the ST) but 3 seems like too much.
I justify not including the Special Editions/prequels by assuming that the people working on the new movies have a love for the originals similar my own love, so their head canon probably involves the unaltered originals and not the Special Editions.
