I've been saying it'll be March for months. Looks like I was right! Looking forward to it for sure! I'm not expecting Casca's condition to be fully cured here, but we should learn a lot in this episode. At the very least, we dive into Casca's mind and learn about what exactly is going on in there. It'll also expose Schierke and Farnese to the Eclipse in some regard, and that should be an interesting thing to see. We've been waiting so long for this moment and it's finally happening. It's almost surreal.
On another note, the translation for the bubble in the preview supposedly says "Wonderful 100p full volume!!". As others have said, I'm assuming this is going to be a recap leading up to the episode. But in the past, wasn't the recap directly referred to as such? If so, maybe this is something different after all. Could we be so lucky as to get 100 pages of new material? I'm not expecting that at all, but boy would that be grand...
