if you haven't seen anything regarding the new era, you can watch the reveal video and more in depth stuff here
personally i'm very excited to see what they do with the new era stuff. the idea that the guys can somehow live on through these virtual idol versions of their personas is neat!! i hope they take the hatsune miku route and make some voice banks as well. there's also some really cool opportunities for new costume and stage design for concerts whether they be in person or virtual. the only thing that's a bit jarring/uncanny to me is the existential bit of how they're living forever now in some strange way. but they're cool with it, so i'm cool with it too. what do you guys think they'll do with the new era?
