I'm not sure if that kind of headline is just supposed to be a marketing ploy (hello, Haruhi!) or if it actually means they're doing some kind of revamp, AU, or otherwise atypical sequel project. I guess only time will tell!
Atypically, the announcement posted on 2ch also reports that a second season of Nogizaka Haruka no Himitsu, the tale of a young man who learns that the perfect innocent idol of his school is actually a hardcore otaku, is also in the works.
I'm not especially a huge fan of either show, but I know a lot of others were-- which one are you more excited about?
