The twitter account of the masked Kadokawa producer, Seiichi Ichiya tweeted earlier today that three of Kadokawa's series, Sora no Otoshimono, Omamori Himari, and Kora wa Zombie Desu Ka? will be getting announcements this month.
According to the latest information, the announcements for Sora no Otoshimono and Omamori Himari will happen sometime on November 11th. The announcement for Kore wa Zombie Desu Ka? will take place on November 14th during the 4th "×× Book Walker" Nico Live broadcast which includes an Kora wa Zombie Desu Ka? illustration contest, which can be entered until the day before the broadcast, and a guest appearance by the author Shinichi Kimura.
What are these announcements? No hints of any sort are given, but one would probably suspect that the one for Kore wa Zombie Desu Ka? might finally be more info on the already announced second season. As for the other two, Temple Knights speculates that Sora no Otoshimono will be information on the BD/DVD release of the movie and for Omamori Himari... umm... guesses anyone?
