Thanks to Nicole for the heads up on this. I'm not sure if this was an officially sanctioned video from ABC or not.
Hi Dark, I was just taking a look at the Barracks Round Up post over on lostargs.com and they have a video which was taken at the reveal. At the end of the video there are a few fast pictures.
The first thing that came to mind when I saw him was: "Is this the new Dogen character?"
