Yup Chewie is dead in the book, but lives on in our hearts! Okay that was way sappy... but I agree... what happens on the big screen is what I go with. So as far as I am concerned until George makes a movie where a moon falls on Chewie and kills him, Chewie still lives. I don't follow the expanded stuff much... I just like the movies. Heck comics had boba fett going by a different name, Jester Merell I think.. and they even developed a back story where he grew up on a planet called Concord Dawn... um... George didn't go with any of that stuff, as in the movie they call him, Boba. Plain and simple, Boba.
I like how the movies have developed Boba... I hear he's coming back in the next and last movie.
