Well, I suppose it is from a certain point of view of here. Because if somehow Padme could be there, what about Qui-Gon, Mace, Ki-Adi-Mundi, Kit Fisto, Plo Koon, etc........

Right now, I am thinking ROTS will show just the right explanation, of how Anakin really does a physical death, but more importantly a death of his psychology, his existance as a person at all. In other words, the change will be so complete to Darth Vader, why he doesn't then show up old will work better. And Luke will be proven right with the words, "Then my father is truly dead."
