Fire Emblem Heroes - Book Ⅴ Ending Movie

TL;DR: It's hard to say.

I mean, IS does think we're running out of characters to add and you've seen the recent banners, they've resorted to making Fae a Legendary and adding Hardin's guys instead of releasing some of the more popular canditates. Probably because they're saving them up. Clearly, they don't want FEH to end, since it's Nintendo's biggest money printer in the mobile game industry, but it eventually has to, because who would pay money for Ionius IX, you know what I mean? I'm exaggerating, of course, but eventually we'll have to reach a point where the majority of the fanbase is satisfied with everyone who has been added. And that's when FEH will end, because they can't make money out of it anymore.

But that's just from a monetary perspective. If we look at it plot-wise... it could go on forever. They could drag this Norse plot on and on, they don't even have to, they could easily introduce Greek Gods or something.

Hell, they could even drag it on until the next FE game that isn't a remake comes out so they can print money again. Or they could add Warriors and Cipher units. I don't know, I'm not IS.
