Ideally, "The Lost 20 Scene", a leaked early draft of the script has additional Jar Jar scenes with the whole diplodect thing (which I would dub and rewrite), there was a scene where a ship made the jump to hyperspace (like in the OT) which was cut, there was a little scene with Anakin and Padme's dad, there was the whole subplot with the original Threepio puppet that Padme finished putting his platings on while Anakin was looking for his mother, there was also a little more Owen & Beru with Padme, and there was more to the Yoda/Dooku duel where Dooku was using 2 sabers and still couldn't hold off Yoda, which made it much less a stalemate and more of Dooku desperately saving his ass moments before Yoda was going to take his head off. I remember Yoda's last line was something like "The end this is for you." right before Dooku pulls that pillar down on Obi-Wan & Anakin.

I don't really know what will be included and what won't, yet, other than being fairly certain that the "Lost 20" will be, because it was the scene most bitched about not having been on the dvd release. And of course it will kind of depend on how good the scenes are that are included.

I've seen the additional scene for the Geonosis Battle in Episode II with incomplete effects and it was nothing to write home about. They had it up for download on Hyperspace a few years ago.

With Episode III, I'm hoping they include the earlier scene where Obi-Wan goes to visit Padme, further establishing their friendship, and the scenes of Anakin percieving a love triangle that's not there, which Palpatine of course eggs on. If you read the script, there is a lot of closeted Anakin jealousy toward Obi-Wan that was cut out early in the film.

Is it wrong that I really hope they haven't finally gone back and completed the Liam Neeson scene for Episode III? (it would really take the piss out of something I already did that I haven't released yet)

Oh and of course there is the digital Yoda in Episode I, so I'll probably go back and add that to "Balance".
