User blog comment:Manuel de la Fuente/Hajime Isayama talks about the ending of Attack on Titan (June 2016 interview)/@comment-24036697-20160818015743

I can't wait; I just hope he doesn't rush things to meet his deadline.

After the developments of the last few chapters, here's what I want to see happen:
 * 1) Revealing what's in the basement. (this one logically will happen in the next chapter or two)
 * 2) Revealing Zeke and Grisha's relationship. (also likely to be seen in the next few chapters)
 * 3) Leaving the walls and discovering the homelanders' true intentions.
 * 4) Return of both Annie and Ymir, or at least wrapping up their stories somehow.
 * 5) Death of Reiner. (he's always been one of my favorite characters, but his plot armor has to wear out eventually)
 * 6) Eren and Armin going to the ocean. (I feel like this would make the perfect ending for the series. The two of them, and perhaps Mikasa as well, sitting down at the shore of the ocean and gazing out at the horizon.)
