My bet would be that the next Green Day album will come out on 2028 or later. That gives them at least 1.5 full year off from touring. On the meanwhile, I do expect to see some shows and/or new albums from some of Billie's side projects. I'd be surprised if they don't do at least a couple of PHGP shows next year, even if it's just in the bay area, as they put out this new album right in the middle of the Saviors cycle, and haven't done a a single show for that.
