I will check with HBC... I am sure the answer will be in a couple of parts... for items on the list with a fixed edition size... you are probaably correct - a retirement would be announced as they can;t make more if they have reached the max... for open editions, some thought will have to go into the retirement. And some of them are all ready retired, like the event pieces which were only made for that specific event and I guess didn;t sell out at that time.
Anyways - it's almost Christmas, so go shopping and get your wish lists into your favorite dealer as soon as possible --
Because... one thing I did find ut is that some of these are in VERY limited supply and WILL sell out quick - it will be first come first served for dealer orders AND I have also been assured that they will update the list nightly... so as orders come in and get filled, and items sell out, they will drop off the llist and be "gone, gone, gone!"
Good luck everyone
