So there was a signature edition run done. I'm guessing different piece means a signature plate or something since it was also mentioned these were done on the same run. I'm not overly shocked here since CC dodged talk about signatures awhile after bringing it up. We'll have to wait and see but there's a few logical reasons why it's existence was withheld. The most likely being they haven't been signed yet...IF they do get signed.
It's not worth raging about. It's probably going to see a premium price hike for it's release on top of the charges to cover the costs of a signature. So it's not like a hundred dollar difference kind of thing. Wait and see then rage if required. I have a fair idea of price so I'm happy with what I've got
