A little research to find somewhere to watch the new episode turned up the information that episode 11 will be delayed until next week. The reason given on ANN is ‘self-restraint’, namely respect and probably a diversion of resources to disaster-affected areas for the moment. Obviously, anime isn’t the biggest thing going on in Japan right now.
ANN also mentions writer Urobuchi’s comments that the last couple of episodes would benefit greatly from the extra week to polish the art and animation. It would be a pity if low quality marred the finale of this show, so I can only approve. In the meantime, ‘self restraint’ is the least I can show for Japan.
