I can see him take a break to write the script of the next batch. But depending on how he manages his time, he could do both. His health issues are another factor too.
I actually WANT Togashi to take a small break after he finishes this batch for publication. By small I mean take the month or a couple months off and take it easy.
If Togashi is ready with a script for a new batch in six months time then we are golden.
Note I would be expecting the manga to still be on the first batch.
Even if it's only a volume a year or even every two years if another indefinite hiatus can be avoided at least for some time then I think
that will be good for the fandom.
I don't mind waiting. It's the not knowing
that sucks. Because even if it's a long wait
you can just hibernate until the next chapter.
