I hate taking anything from GER but I saw this as an article from Engadget earlier and they also had a reference to a separate leak found on Reddit. So it's something.
Hopefully the Signature Edition is a good replacement for my long-in-the-tooth Voyage at some point. I also hope they have made the move to USB-C as well.
