>>73774343People noticed something similar with Pomu being mysteriously absent in future material promos a while before she graduated, although I wouldn't think this translates to the rest of the branch graduating - that sounds too good to be true.
I don't think they would kill the EN branch honestly, because it's their last and only actually-successful (formerly, that is) foreign venture and it'd look probably bad to investors to basically say you're giving up on overseas expansion. I'd more of guess EN branch is truly the black sheep and they'd rather segregate it from everyone else. Which is a massive mark of shame in its own way but hey.
