Okay...
So, while I really don't have a problem with this change...
I do have one observation:
If Anakin dies when he falls in the lava, and then lives the rest of his life as Vader, and then comes back at the end of "ROTJ" as Anakin again because he returned to the light side. Then in reality, he should be standing at the end of Jedi as a blob of flesh with a head....because he returns to the light side when he kills the Emperor...as at that moment, he becomes a Jedi again....(hence the title of the movie: RETURN of the JEDI)
But, I'm willing to thrown out this bit of logic in this case.
I'm a hard core SW fan...I have been since I saw 'Jedi' in the theaters when I was a kid no older than three. And I have no problem with Lucas making improvements to these films....sure, the technology exists to improve the films...so, fine...do it. But don't change them. Fix the Max Rebo band scene, but don't turn it into that Jedi Rocks crap. Add a descent clip of Vader arriving on his star destroyer, but don't change his dialouge from "Bring my shuttle "...to alert my star destroyer to prepar for my arrival"....it's just lame. So...fix them and update them, but don't change them. ....Unless it's an improvment....
and if he can't figure out what are good changes, then he can call me anythme and I'll let him know
On a good note, he has added a lot of footage to the lightsabre duel in Empire Strikes back....it'll be a lot more intense than it was originally
