More rumoured changes to the original Star Wars trillogy
Check the link for the list, but here's a couple that makes me shake my head.

From a New Hope
12. When the Death Star destroys Alderaan there's a new scene of Yoda's reaction to the disturbance in the Force that is created by all those deaths and then it cuts to Obi-Wan reacting to it as well.


18. The Obi-Wan/Vader duel has been spruced up. It is much more epic and there is much more movement. A modified version of Duel of the Fates is being considered for the scene.


From Empire Strikes Back
08. A new scene was shot in which the stormtroopers, after they capture Han, Leia and Chewie, bring Vader the box containing C-3PO in pieces. Vader orders the stormtroopers to bring the broken droid to Chewbacca's cell so that he can fix him.

And from Return of the Jedi

12. Sebastion Shaw who played Anakin when he was unmasked has been replaced with Hayden Christenson in make-up to make him look older. Anakin has much more dialogue. He apologizes for the destruction he caused, he thanks his son for turning him back to the light, he tells his son to rebuild the Jedi and he says he loves him and his sister. Just before he dies he says, "It is finished...".

I await your rage.
