>>2 Sentai has the rights for it. I hope if they dub it, it's good. I mean, I'll still buy it when it comes out, if only for the sub, but if they screw it up as much as they did K-On... D:
Sentai's site says it will be released on DVD & Blu-ray this year sometime.
I'm at about the same spot you are, just watched episode 4 last night, watching 5 in a few minutes. Since it's a notaminA anime, it will most likely not get a second season, though :/
