Just finished Re-watching the series. Just watch last episode today, Searched on "news" for zero no tsukaima, and found this:
Zero no Tsukaima Series 4
I don't read an awful lot of manga, I prefer to watch anime, and despite what anyone says, this is one of the best anime in my opinion. Since the main character is likeable and useful, The show is serious yet fun. Not to mention I love fantasy setting.
Well, yeah, enjoy! Best news I could've hoped for.
