The director only admit that they have problems finishing production of the last 2 episodes on time (on his blog he mentioned that even the Ep10 was just barely making the deadline), thus they need to fill the original time slot with (yet another) recap episode schedule for the 24th Dec.

Since most TV programmes in JP terminate just before and during the New Year period to give way for various special programmes, and the new Spring TV season not starting until mid January, the last two episodes can only be allocated after that, thus the March-ish time-slot.

I do hope that they are using this 3 months time well to write a better ending, as I've heard rumors that the production company's high ups originally do not have high hope for this show, and they only planned it as a one season only. It is a surprise to them that this show is a big hit and is now topping the chart for BluRay pre-order.

The only hint for S2:
On the last paragraph of the director's blog post, he wrote:
私としては、第12話の完成をもって、この物語のすべての終わりだとは考えていません。
(I personally believe that the Ep12 will not be the end for this show.)

応援してくれている全ての人達にこたえられるような何かしらを、どこかで必ず示したいと思います。
(I will do my best to thank the many fans that have supported this show, somewhere, someday.)

Yeah. Seeing as the Actas is really small, the fact that this was such a big hit is something they didn't think was going to happen. Hell they beat out Chuunibyou and SAO with no challenge. I think this is the birth of Thank-You-based-Actas in the process.

It's reassuring that this show is topping sales charts for fall season. one, it means chuuni isn't at the top and 2 it means this might get a second season

Huzzah to both of those.
