I have a feeling this is the only Voyage we'll ever see. Most devices are replaced after a year with new model and this hasn't been. There were rumors just before that year was up and then they died out after. I haven't read about any rumors for a while and I read the tech and ebook blogs all day long, being retired.
I realize that I also haven't given you a decisive answer and I await my well deserved snarky reply.
