I tell you one thing that disappointed me in regard to the DVD release of the original trilogy.
I wish Lucasfilm would have suped up the EP4 lightsaber scene in the DVD release. Instead they just used the same old original footage. That duel is kind of a let down if you watch the movies in chronological order. Furthermore if you play through the EP3 game for PS2/XBox, you can unlock that duel (Vader vs. Kenobi on Death Star 1). THAT is how the duel should have gone.
I'd have loved to see Vader and Kenobi doing flips and stuff. Don't give me that "but they were old" stuff either. We now know that Kenobi was in his late 50s, and Anakin/Vader was in his 40s. That's not that old. Add in the Force component and they ought to be able to do some cool stuff. Let us also not forget to mention that Darth Vader had cybernetic implants. Look at the 6 million dollar man, or the bionic woman. Vader should have been able to crazy awesome stunts even without the Force.
Look at Yoda. He was 800+ years old by the time of EP2 & EP3. He was doing crazy mad moves guided by the Force. Look at Darth Sidious in EP3. When dueling Mace Windu he was doing cool acrobatic moves too. I'd figure he's no younger than the 50 age mark. Nope, I refuse to even acknowledge the whole "old fellas" concept.
Again I'm not referring to the original footage or EP4. I'm saying Lucasfilm should have rendered new CG content showing a more spectacular duel. Sure keep some of the original footage, but add in all new stuff and make it hella awesome.
I guess we'll have to wait for the next time GL releases the SW anthology.
