When it comes to Nijisanji he has done nothing but bait even saying he is going to say something soon tm before the Aster shit made people look at that instead.
He has done little besides vaugepost about shit in Niji that seems pretty obvious or not too impossible, such as graduations or internal strife. Considering how Niji has been on a steady talent bleed and sometimes people are visibly upset, its not hard to theorize shit is going wrong and end up right if you say people are graduating soon
