^Maybe the person I got this news from got that part wrong, maybe got confused with the special episode announced at the same time. I will check this out. Hopefully you are right, my harddrives are about to start a strike any moment and dropping the thing to half an hour will make things easier for space. I found a little more info on the show but apart from airing time, the time the program starts, they don't say the length of the program.
It is said that the program will consist of music, dance, konto, single and theater song coverage and of course the documentary stuff. I wonder if the thing, all these things, will be wrapped up within backstage footage. Maybe they will do konto improvisations or something, or some members will be host/co-host backstage and will start stuff with other members. Seems interesting.
About AKBINGO! going off air because of this TV program, AKBINGO! is in NipponTerebi and this one goes for NHK so I don't see any reason to cancel it because of this new one. Unless, of course, there is some resources, like budget, being redirected or something.
