It's an interesting idea, but I can't vote on anything I'm not certain of being completely legitimate.
After reading the "source rumor" from the Preproduction Thread, I took it in jest because you know how those things are. I have a feeling the person, if actually hearing some early mixes, might have been hearing insturmental version of lyrical songs similar to the tracks on The Boys in Brazil second disk on Rush in Rio.
I could go either way, when you get down to it, this is band who are known for their musicianship as much, if not more, as songwriting. Even though I love Pearts writings lyrically or novella, why not work with your strenghts?
Whatever they do, I'm still in. They had me at, "A modern day warrior..."
