Remeber when TPM came out and everyone was questioning why Qui-Gon's body didn't vanish, and he become one with the Force? George Lucas in an interview said there would be a hint in Ep. 2 That would answer this question.
Does anybody have a clue as to what it was/is? Or do you think Lucas dismissed it from the movie? One comment on this issue is that many Jedi died in the final battle, and I did not notice any of them vanishing and becoming one with the Force.
