[Black Panther] Will T'Challa be the last Black Panther of Earth-199999?

After being given the heart-shaped herb, Killmonger had the rest burnt. Nakia, of course, grabbed one for M'Baku, but ended up giving it to T'Challa. So... is that the end of the Black Panthers?

If I've learned anything about comic books, the answer is no. They could go to another timeline and steal one, they could synthesize it with some help from friends, they could retcon some more in. It looks like there aren't any at the moment. But we won't know for sure until it comes up again.
