I heard a rumor about season 3 coming out this June or July. Though keep in mind, this is only a rumor. I've heard that Rosario + Vampire season 3 is suppose to come out in June or July as well, so this rumor might just an educated guess based on the Japan's recovery rate from the earth quake, not to long ago. That's all I know so far. I just finished watching Sekirei: Pure Engagement about an hour ago and am planning to research the season 3 rumor a bitter further. I'll inform you if I come across a new finding.
