No Julie Benz for Halo 3?

Miranda Keyes but not as we know her...

Over at there's an interview with Julie Benz (the Buffy and Angel star who played Miranda Keyes in Halo 2) including some intriguing information about Halo 3. Are you all done with your voice work for the Halo 3 video game?
Benz: You know what? I am actually not a part of Halo 3. I was informed a couple of weeks ago that they are actually changing the voice of Captain Miranda Keyes, and giving her an accent. Are you serious?! What kind of an accent?
Benz: I have no idea. [Laughs] They didn't even entertain the idea of having me do it, so... I was very sad. I was very sad. I had such a great time doing Halo 2.

Bungie giving Miranda and accent?? Why?

Sure, many have voiced over the years opinions about her less than perfect dialogue in Halo 2, but why do Bungie suddenly feel the need to disrupt continuity in such a way?

Of course, it's completely possible the accent rumour is simply an AIB (Actress Interview Blunder), but either way, it looks like we won't be seeing Julie Benz returning for Halo 3.
