This anime is quite old now and was created by the same person that made Sao , he was actually doing both amines at the same time accel world ended first tho becomes it did nt really have a season 2 like Sao did

Sao is still not confirmed for the 3rd season , not by the producer anyway ... People say they will make one due to popularity but I don't know due that the Ike that has already passed

Also I have seen a image of what seemed the next anime from the producer of Sao but this only comes out in 2014 , so have faith because 3rd season of Sao ( gun gale online )might come after that no promises tho

I got this of a anime news website I can't remember what it was called
