...or so rumored.
From:
http://www.millenniumfalcon.com/Episode IV: A New Hope DVD:
* LightSabers changed for Vader versus Ben Kenobi Death Star duel.
* TractorBeam control now in Aurebesh.
* Han and Greedo scene slightly changed (everyone\'s seen this).
* Jabba the Hutt redone from Special Edition Jabba.
* Boba Fett still mugs camera.
* Han still steps on tail, "You\'re a wonderful human being," still there.
(The scene is an improvement over the SE, but still not great.)
Episode V: The Empire Strikes Back
* Emperor replaced with Ian McDiarmid.
Dialogue in this scene has been slightly modified, indicating either that the Emperor knows it was Luke who nuked the Death Star, or that he is Vader\'s son. Maybe both. Otherwise, dialogue remains in tact. Emperor\'s theme from Jedi also added into the scene.
Episode VI: Return of the Jedi:
* Hayden Christenson has replaced Sebastian Shaw only in the Force Ghost shot.
* Line about Leia remembering her mother while talking to Luke on the Ewok Village veranda has either been omitted, or modified.
* Naboo has been added to the final planetary celebration montage at the end of the movie. It is a shot very similar to the helicopter shot of Theed in TPM when AATs are moving up the street towards the palace.
Original Trilogy Bonus Materials Extras:
* Episode III teaser trailer.
* Episode III Vader "making of" featurette.
* EASTER EGG: Warwick Davis short film of Wickett the Ewok fighting Boba Fett on the Death Star II, shot as a gag during the filming of Return of the Jedi.
Episode I DVD ReRelease:
* Puppet Yoda has been replaced completely by CGI.
