Anyway when CSP0 get's blasted by a storm trooper off screen...

I wonder if the original or special edition dialogue will be used... But the main point i wanted to raise was it actually does not sound like a storm trooper...

I think the sole reason the voice is so different from the way Stormtroopers sounded in ANH is simply because the audience would automatically know who it was. While we could still figure out it must be someone bad, you don't know the motivation behind it, thus making the reveal of Darth and Boba a shock (especially to those of us younger than 14 years old).

Maybe it doesn't matter as much now, since we know who it is.. but I could go either way (with keeping the original gruff voice, or something akin to the Stormtrooper higher pitched and modulated voice in ANH).
