I think it might go further than that, with Yoda and Obi Wan be throughly defeated and fleeing to there respective hideaways.
I mean, they are being pretty lame come Episode IV/V, one hiding in a bog, the other pretending to be mad in a desert.
They must get their arses pretty whipped to not even try to stop the empire.....
It is said that vader hunted down and killed all the remaining Jedi, i'm looking forward to seeing some real dark action as episodes I and II where all too light and jolly for my liking.
padme dies or disappears and is presumed dead. jar jar binks dies. mace windu dies. anakin turns into darth vader. yoda and ob1 goes into hiding. leia is given to senator. ob1 sends luke to his uncles. the empire grows. the death star gets underway. hunting of the jedi. vader gets a red light saber. ob1 ponders how he had failed. anakin deals with his anger inside of himself and couldn't control it. what more is there to say?
the last scene could be with Anakin, and I am inclined to believe so only because this has the feel of a dark movie...if it ends ( as I sometimes hope) with Luke and Leia's birth and uh banishment of sorts to diff planets, then there will be a bit of a happy moment....even in the midst of the sadness that the "heroes" escape tofight another day....
