This is kind of a minor personal concern, but, before I had TESB on VHS (NTSC), I had "The Story of the Empire Strikes Back: The Adventures of Luke Skywalker" on audio cassette. So, after I got the VHS tape, I was a little disappointed that this line of dialogue wasn't there. So I hope it will be intact on TESB Revisited...
On Hoth, after Luke is out of the Bacta tank and Threepio says it's good to see him fully functional again, Luke says: "Thanks, Threepio." On the VHS version, which I'm assuming was the theatrical version, Luke's line was taken out, but the line is in the Special Edition.
So why does this concern me? I guess it's a line that shows that Luke had actual friendship and respect for Threepio, as he's usually getting verbally abused or shot at by just about everyone else throughout the rest of the film. (LOL)
