For anyone browsing old posts, I just want to say that VOLUME THREE IS AVAILABLE ON AUDIBLE AND ITUNES! WHOOHOO!
It really stinks that they won't give you any sort of update at this point. They have had it for months now, I'm hoping that something isn't wrong.
No update yet, I'm afraid. It's in audible's hands now. It could be ready as soon as today, or it could be several more months...
I think a realistic estimate would be some time before Halloween.
