Kotaku released this article without any links to their discovery so I did some digging but couldn't find a source for the information, so I looked up Nintendo's Japanese news because the article insinuated that it may be only in Japan the plates are released in. And I discovered the location of the information was the Japan site for Nintendo's newest announcements, I translated the page with Google and found out exactly that these are planned for a Japan release (possible November 2015). As of yet I don't know if they'll be coming to the USA.
