avex consists of more than just the label.
E.g. some artists are only distributed by them ( some K-Pop bands or Johnny acts e.g.).
Some are also under avex management like Faky ( + they also have their hands in other stuff than music).
And their management is doing an awesome job as they're the ones scoring all those deals and making the music connections and their schedule.
So no, I don't see them switching labels as they're a through and through avex act.
avex, the label, is apparently suffering a bit more (tho it's hard for the whole indistry rn, others have switched the place of headquarters e.g., too), but I highly doubt they vanish from the scene.
