First of thanks for experimenting with this.
Saki's next season (
thread here) will air in spring 2014 (
source here)
How does this work for movies though?
Aura will be released in theatres
on April 13th so that would make it spring 2013, however most people won't be able to watch it until the blu rays come out, so should it be that date that's indicated? (if so then there's no announcement yet)
