I thought in light of the recent spoiler deluge and with the novel/comic out, it would be interesting to revisit this question. Sometime back, Pablo said this in his QA thread: "One of things I am curious about the force ghost thing that is set to be explained to us in Episode III, is the nature and importance of that revelation. My question is, does the ability to retain one's spirit after death turn out to be of great importance plotwise for what happens in Episode III or even in 4,5, or 6? Or is it just stuck in there just as if to say, "ok here is this nifty little thing they can do and here is how its done" with no more significance to it explained than that? In other words, is it there just as a wink to the fans or does it TRUELY have major plot significance? Thanks" "You know, this is one subject that I am avoiding, for a variety of reasons. But I will say this much -- Episode III really adds a subtext to the last shot of the Jedi spirits in ROJ that wasn't there before." Also of note is that in the RotJ DVD commentary, GL says that Anakin's body did NOT disappear. Obi-Wan and Yoda are the only two to disapapear on death. Another point: GL said that Anakin was able to retain his identity because Obi-Wan and Yoda helped him to retain his identity after he died. And of course, spoilers show that Qui-Gon's voice tells Yoda that identity can be retained, and he will teach Yoda and Obi-Wan. So.... what in RotS explains why GL took the drastic step of changing Anakin's ghost? After all, Qui-Gon says only Jedi, who are compassionate, can do this, the Sith cannot. Anakin is compassionate in RotJ when he saves Luke. So why change from old Jedi Anakin?
