The biggest question on my mind now is where do we go from this arc? How does one up up the stakes further than a tournament involving every current universe with them losing meaning destruction? How does one go futher than that? Perhaps maybe we'll finally get a close to end of z timeskip, or just some stuff involving another universe like with Future Trunks arc.
I know Toriyama will find a way but i'm really really curious what the arc after this will entail. Yeah I don't think it'll happen personally. He'll probably just be another Whis/Vados type and do Zenos bidding.
Easy, have an enemy strong enough to wipe out entire multiverses.
