Yeah, derekweb, that scene had to have 2 blues against each other. In fact, the ending of the movie felt like assorted scenes of how the end of this movie ties in with the beginning of the next movie. The was a specific scene where Obi Wan picks up Anakin's lightsaber off the ground in Mustafar, and I was going hmm... that's subtle.
I think they've answered practically everything except one that comes to mind, which is: Why the heck does Yoda and Obi-wan disappear when they die by not Qui-gon? Or everybody else, in fact, in the prequel movies?
