Isayama recently reiterated that he aims to end the manga in 2020: https://www.crunchyroll.com/anime-news/2019/12/28-1/hajime-isayamas-new-years-resolution-end-attack-on-titan

Though every time we calculate the number of the possible final chapter, the manga keeps continuing past that (I remember when we thought it was going to end in Volume 30, ha).

An October ending certainly looks like the most likely option now given the slow pacing of the latest chapters. The story surely won't end in 2 chapters and very likely not in 6 either, 10 chapters sounds more plausible.
