This week's Madoka ep11 has been officially delayed. No station will air it this week.

EDIT: ANN article: "This week Madoka Magica not aired in self-restraint"

EDIT: By extension this means episode 12 is delayed as well. It is currently unknown what the next air dates for either episode are. ~Solace
