The official site updated their BD/DVD
listing with design images of the
cover/packaging and
first box. They also updated the details about the included extras.
The first volume will contain episodes 1-3. The extras include the special cover image, the first non-text opening, and two types of audio commentary for the first episode on the BD. Track 1 will be character commentary by Ohana (Kanae Itou) and Tomoe (Mamiko Noto). Track 2 will be standard commentary by Itou, the director Masahiro Ando, producer Kenji Horikawa, and producer Takayuki Nagatani.
The first pressing of the BD will have the special artbox linked above and a 64 page all color booklet. The booklet will have the opening and ending rough cuts and original images as well as a 6 page draft from Jiroumaru entitled "The Bubble-smothered New Employee Training Session".
The DVD only has the special cover art and the non-text opening on its first volume.
