Oh, alrighty then! thanks for clarifying that for me! I remember now that Miyamoto said something along the lines of that they would pretty much have to do it with Zelda.
Not sure if they actually confirmed that they're doing orchestrated music, so correct me if I'm wrong.
As for the choice between the music or VA, I'd choose orchestrated music without hesitation. It was amazing in Mario Galaxy, and now I can just imagine what it would be like in Zelda.
