Is it wrong that I find the new line both horribly amusing and entertaining? It must be the tone... It's gotta be the tone!

If I recall correctly, "alert my Star Destroyer" is an unused line from the recording sessions for Star Wars, and is why it sounds so odd. Take a listen, then watch the original film (the non-Revisited version with the original audio); it really does sound more like it fits there than in ESB, where James Earl Jones pitched his voice to the way we're now used to hearing it. Ol' Vader was a bit more of a higher-pitched hothead in that one, particularly when interrogating Rebel prisoners on captured transports. :-)

I'm pretty sure the new line was recorded specifically for the SE. Just like Boba Fett's new voice and the new Emporer Hologram scene. If you compare Vader's voice to how he sounds in RotS, it's a match.
