Has Genshin ended yet, if so, what happens next?

Teyvat chapter still didn't even finish. Devs said they want to expand the IP for 20 more years or so.
long way to go buddy.

No

No, it won't end until it stops making money.

The only thing that could end Genshin as a brand at this point is its sequel (as in, it is done poorly).

You're a tourist

It's almost there. Slated for it is Genshin 2, literally. Like chapter 2 (not a new game lol).

no

Bruh we still got ten years at least, twenty at most.
