I've never understood why the fanboys (and I guess I am one, or I wouldn't be here) get so worked up over Greedo shooting (kind of) first but don't seem that bothered about this scene which, for me, is the worst travesty of the SE editions. I don't believe Burtt who says it's leftover dialogue from A New Hope - in fact, since Revenge Of The Sith I have very little respect for that fella and I'm glad he's no longer part of the Star Wars team.
I hope and pray that common sense will prevail at some point and the line "Bring my shuttle" will be re-inserted and all the additional scenes of the shuttle flying to The Executor will be removed - we don't need them; we're not stupid - we can make the intellectual leap that Vader goes to his ship without being shown.
