There's always lots and lots of things they could do, but it's never about that. High School of the Dead, for example, isn't finished, it was dropped. Whether the story of an anime is finished or not has no bearing on if the studio adds more episodes. In both HOTD and KLK, not enough Japanese people liked it to keep it going. I will not guarantee anything, but KLK is most likely dead. Forever. Hell, this may well be the final post of this Wiki. I have carried this wiki on my shoulders for months during its inception, and now I bid it farewell. Goodbye dear KLK wiki, I mourn your death. Too bad it wasn't better and more popular. Oh well. Better luck next time.
Well, Kill la Kill was licensed by Aniplex in the US, and by Anime Limited in the UK. The first volume was released on July 15, 2014 for America, and November 17, 2014 in the UK. This could indicate that the series was taken more seriously by the American anime industry than the UK anime industry. It also leads me to think that KLK is ever so slightly leaning towards America rather than UK. Also, the main headquarters of Wikia is in the US, so I think American English is slightly more appropriate.
