Given that arcs usually span 16-20 chapters, the most likely dates are either this October (Chapter 122, Volume 30), or February 2020 (Chapter 126, Volume 31).

It'd be too rushed for the manga to end in the next 4 issues so my bet is the latter. Plus, considering that Isayama revealed the final panel and that he said at this moment that the manga will end in the following two years, that make sense.

I think we can hope for the Marley arc in 2020, and a bit less than a year later, the final arc. A bit like what happened with season 3.
