I heard a rumor that said it was coming in June.
And for those that want the links to the fan translated novel, I think
http://s15.invisionfree.com/Zero_no_Tsukaima/ has the links. As well as the manga links. They also have a few images from the new third season.
All I know is I am very excited about a new season, very excited.
Although I am sad that it seems they are skipping ALOT of novels.

What do you all think about them skipping ahead? Kind of puts a damper on the idea of a soon to follow season 4 since they are skipping alot of story arc and novel material.
