Those release dates are most likely based on the sales figures of the two sizes that are currently available. And if "published" forum interest is any indication, I'd say (in my totally unprofessional opinion) it ain't happenin anytime soon. These things have been a discussion "dud" around here. Nobody talks about 'em. It's like they don't even exsist really. I have the smaller one and it's freakin awesome! It's displaced my Shun to the point that I've listed it for sale. Nothing against the Shun it's just that it isn't needed (or even desired) anymore. The Sikayo is THAT good. A kitchen knife is a tool that you're gonna use on the average of six times per week FOR THE REST OF YOUR LIFE. Did you get that? FOR THE REST OF YOUR LIFE!! That's almost every day. Cutting onions. Slicing tomatoes. Chopping celery. Mincing garlic. You name it. Why not use the very best? And no, I'm not talking about snobbish Japanese kitchen cutlery. Been there, done that. Japanese kitchen cutlery is great. Well worth the money too. Until, that is, you get your meathooks on a Sikayo. Then, well, those Japanese pieces have to compete for cutting time. And they do... For a while... Then the Sikayo becomes the "go to" piece. This happened to me. Get one of these. It will happen to you too. One of these days these CRK kitchen knives are gonna start getting the press they deserve. Be in the crowd that gets to say, "hey what's the deal? I knew about this back in the late 00's. What's all the fuss?"
CRK could work on the price, no doubt. But don't miss this piece. The sixer is way handy. Don't have any experience with the nine-incher. Cheers.
