The kanto starters stayed. Oshawott is not hated like Tepig
Since when is Tepig hated? some people don't like him, just like some people don't like Oshawott, that doesn't mean they hate him or if they do, its not everyone its some people.
Answering the question, unless we get a Johto of Pokeamerica after Isshu and the starters get rotated out like the Kanto ones by the new ones I can still see Oshawott appear once in a while with the new starter/s having more focus, otherwise no.
Piplup is still adverstised and he is out of the anime, they can keep milking Oshawott even if he isn't there, Piplup is in the cover os Pokepark 2 lol with only Isshu pokemons I believe.
