Now that you can watch them all in order, there's a new view to the story. With the original three movies (Episodes IV - VI), they make you think Luke is "the one". (Who will bring balance to the force).

However, when watching all six in order, the suprise is that Anakin turns out to be "the one" all along, he just took a very winding path to get there.

That could make for a really bizaare Episodes VII-IX, along with the "Episode 0" (The early days of Yoda) that Lucas was talking about a few weeks ago. (http://www.moviehole.net/news/5674.html):

The whole thing could have been staged. Yoda could have known somehow that Vader was the one, but knew the rest of the Jedi would never go for it if they knew the risks of what would happen with the whole Anakin/Vader/Empire thing, so Yoda had to sneakily set it up, and seem to be against Anakin becoming a full Jedi, just to throw the rest of the Jedi Council off. Episodes 7-9 could deal with the after-effects of the whole "Sacrifice Anakin to bring balance to the force" that was set up in Episode 0.  

(Meanwhile, we find out that Chewbacca is merely a gay Ewok on steroids)
