CuSO4 is the one who usually has news, but I'll leave this open to all.

Anyway, I know the 2nd OAV episode of "Sorezore" (episode 24 overall) has "the end"
at the end of the episode, and considering how this story was just plucked from WAY
into the manga series, I'd say that's it.  BUT, is there any news about the series

in Japan (or the possibility of a 3rd series)? 

Further, what were the ratings for the 2nd series in Japan if anyone knows?
