The Nekomonogatari official site has updated the information on the cover of the vol. 2 home video release. Vol. 2 will contain "Tsubasa Family 3" and "Tsubasa Family 4". Nekomonogatari is the story of Hanekawa Tsubasa that takes place before Bakemonogatari and after Kizumonogatari, which is pending a theater release. Nekomonogatari aired in Japan at the end of 2012 as a part of the "Nishio Ishin Anime Project".
The cover of Nekomonogatari vol. 2 features Oshino Shinobu and Oshino Meme. (Sorry it's not a sexy female character, but he holds a very important role in the story, as you may know.)
The release date is set for April 3rd in Japan. The Monogatari series home video releases are also famous for their "Character Commentary" written by Nishio, where the voice actors act as characters to make comments about the story. Nekomonogatari vol. 2 features Kagenui Yozuru and Ononoki Yotsugi. Fans can speculate that both characters may reveal more information about Meme's past, but it's also possible that they talk about something completely random just as the past character commentaries by done by other characters for Bakemonogatari and Nisemonogatari disk releases.
Vol. 1 will be released on March 6. and Character Commentary is done by Hachikuji Mayoi and Kanbaru Suruga.
Below images are special illustration cards that comes with the purchase of the disk, depends on which store you pruchase from.
