I hope we see this next chapter who the shifter Grisha ate to return human and even then, there's still 1 more unknown shifter of the 9 Titan powers mentioned.

1-2 Grisha+Frieda (Eren has both now)

3- Marcel (Ymir has it now)

4- Berolt (Armin has it now)

5- Reiner

6- Annie

7- Zeke

8- Quad Titan (presumably)

There's still 1 more Titan power we don't know who's in possession of it.
