Cool pic, but I don't think "Vader" has any place in the PT. Dark Anakin (who it is assumed, dies) yes, but no Vader.

Or at least no Anakin as Vader. If we could integrate glimpses of Vader, without making it obvious it's a cyborg Anakin, but a completely different entity (which would make obi blaming Anakin's death on him in New Hope that much more feasible) this could tie up the PT and OT nicely.

EDIT: Actually, thinking about it, that still wouldn't make sense with Obi's "who was a pupil of mine until he turned to evil"

GAH!
