you gotta wonder though, is Anakin's skull still in the helmet? (in ROTJ, seems like Anakin/Vader was getting cremated with helmet on, rather then separately........)
Actually, his body should have "dissolved" upon his death. It happened to Ben & to Yoda. Since Anakin was redeemed, one would think he also disappeared into the either.
but only two jedis have ever "dissolved" on-screen (Obi-wan and Yoda), every other jedi in the prequel, including Qui Gon died like a normal person
I thought the explanation was that Qui Gon found a way to stay active or whatever after he died, then he taught that to Yoda and Obi-wan, chances are that he probably didn't share that with Vader
Alas, poor Yorick ...
But we did see Anakin/Vader materialize so its safe to assume that his body may have dissolved prior to the fire. It's also been my belief that Qui-Gonn had appeared to Yoda to tell him that returning in an ethereal form was possible (even though it did not appear on screen).
