That doesn't mean it works the same way in Japanese animation industry. I have read several articles written by a guy who has been closely involved with anime stuff, so I believe I have a quite good idea about these things. Just to be clear though, I'm not saying that they do not work on episodes in advance, just that the work most likely isn't finished till it's close to the deadline. Actually, they are happy if they manage to finish it. You should compare Shingeki no Kyojin TV episodes with their Blu-Rays counterparts.

This is also exactly why more than often, sites like Crunchyroll are unable to keep up with their schedules, because the episodes are delivered to them late. This was happening literally every week with many Aniplex shows last seasons, i.e. Magi or Kill la Kill.
