I've only seen this report popping up on
AnimeSuki's rumormongering forum, and even there it's by no means implied that any official announcement has been made yet. But hoping it turns out to be true, the shounen light novels Steel Maiden Sarah: Diamond Princess (Choukoujo Sarah) may well be getting an anime adaptation.
