Someone has put up an unboxing video for us to see...

Also, here are pics.
There is absolutely no details about the game or the box set on the box itself. Only beautiful art. Also, when I heard that the artbook was going to be hardcover, I thought they'd go back to the bigger artbooks (Atelier Rorona, Ar Tonelico Qoga) as opposed to the ones the size of a game case (Disgaea 4, Atelier Totori). Alas, it was not to be. Still, pretty nice box set.
I'm disappointed about the cards though. I thought they're going to design all the cards this time around but just like last time, only the face cards get the special treatment.
