I can't believe Lucas will kill Obi-Wan Kenobi off, but from the reports I read about, apparently Ewan is having second thoughts about carrying on with the Star Wars franchise and wants to do other projects. I guess he's contractually obligated to work on the next one, so Lucas is rewriting some scenes to bring proper closure to the character. Part of me really hates to see him go, but it could turn into something very cool story wise if GL does it right. I think that Obi-Wan took Luke to Tatoonie for a few reasons: to be with Luke's family, to privately train Luke to be a Jedi, and most importanly, to draw Vader away from the Emperor in order to kill him. (divide and conquer) Yoda could take his apprentice, Leia, along with her adopted father's army, and make a Grievous style raid on Coruscant and go after the Emperor...but that's for another thread. Obi-Wan could somehow let Vader know his son is still alive, draw him out alone to the deserts of Tatoonie, and have a massive kick ass sequel to the ROTS Duel, only this time Vader wins. Though he'll probably have to kill Owen and Beru to get at Luke, I doubt he'd have much problem with that....so then Luke will become Vader's apprenctice. Vader and Luke could then go to take out the Emperor, so finally, with 2 Sith and 2 Jedi going after him, I think the Emperor could finally be defeated. Hopefully someone can explain to me the whole Qui-Gon speech Yoda told Obi-Wan in ROTS...I never really got what that's about, but I think it could be a main plot point in this episode.
