I can still see ATB things on the website (I'm in Hong Kong, so I guess APAC region with restocks maybe from Japan?), but the "in stock" button is not very helpful. It usually shows a lot of things which do not seem to actually be available. Surprisingly I just tried it and the few items I looked at were all ATB (including the Chihiro blanket - never seen that with the "add to basket" button). However, I also searched the Chihiro heel pouch (probably not going to buy but I like it!) and that also shows up as available but was not in the "in stock" list.
In short ... the whole thing seems to be quite random.
