Legend of Zelda: Hyrule Graphics listing shows up on Amazon

The legend of Zelda : Hyrule Graphics was listed on Amazon Japan though there's absolutely no info on that item! We've bound to know soon enough as the webpage mentions that it's "due" in Japan next month! My best bet is that like Hyrule Historia(which details the timeline of the Zelda series)Hyrule Graphics will be a book on Zelda's many game visuals and styles thru the years.
