Nobody ever admits to knowing anything about when they are going to arrive. I have enough faith in the people running Spyderco that I don't accept that. I think Spyderco knows but they aren't telling. The distributors and dealers may or may not know, but if they know they don't admit to much. We do know that it frequently takes a very long time from when the order is placed. If it is something that Spyderco is planning themselves it may also take a long time to produce but they might have started a long time ago before it was ever announced to the public.
There were hints about a year ago of another limited model from a retailer but absolutely not a breath of it since. In that case they might stay quiet until the knives are ready to be shipped then quickly put it up on their website. Or maybe they didn't follow up with the order, we would never know.
