I think that the next one would be just the tournament. So no actual danger or anything. After all...the King did say he'd want one as well.
And we still don't know wtf happened with Trunk. I mean his combi of blue and SSJ Ki. Since he is a half breed, does that mean he gets God Ki from both races? If that is a thing then there is a slight chance of Gohan jumping back into the fray but I think DBS has pretty much put him down as a normal person these days.

But yeah, wasted potential. But..maybe, they killed those Gods recently in the future timeline. Also...we don't know if there are other types of Gods. Like previous God's of Destruction that are sealed away or something. Hell maybe even the previous King of All as a foe.
