As we reported earlier, the NES Classic Edition has been discontinued in North America. It also appears, via an update on the official website, that the same has occurred for the Famicom Classic Edition in Japan. A message on the site says:
This product has ended production for now. When production is being resumed, we will tell you on our website.
We have already reached out to Nintendo of Europe for more information on the NES Classic Edition production in Europe and will update when we have more information.
