Afraid there is no regular release rotation and if there is a schedule only the Busses know about about. And I'm pretty sure it's a loose schedule. Pretty much how it works is that you get it when you see it. If it's in the store then great but chances of it ever being there again are (at leas have been) slim to none. There are other ways to find the blades you want but it requires a bit of diligence. You can check out the Busse exchange over at BladeForums and you may find what you are looking for. There is usually some mark up involved but every now and then you may score at or just below the store costs. Then there's the ganzas and shows... The Busse Kin companies round up anywhere from a few to a lot of various blades and sell them in either online events or they take them to various shows (like blade) and sell them there. You either have to be actively involved or find a proxy to score something from one of these types of events.
Stick around the Yard and you hopefully see an opertinitu at the knives you want. If not it's still pretty much the best knife forum you are going to find. The community here is really good and there lots of info about quite a few topics.
