All Generations the same thing.
1º) Pikachu is the real protagonist of Pokemon, not Ash. But this is one of those cases like Laurel and Harley, you can't have one without the other. Therefore, Ash is not going anywhere because Pikachu is not going anywhere.
2º) The very first time Ash and Giovanni met face to face and battle was in Unova, and it was very short. Therefore, Ash's role in the Anime can NOT be over until they have a rematch and Ash defeats the anime's main antagonists.
3º) The Anime started just like the games (like Pokemon Red, to be precise), so it should end like the games too. Which means Ash battling and defeating Elite 4 and becoming Kanto's Champion.
4º) The only way for Ash to be "unbeatable" would be if Ash someday catchs Mewtwo, the world's strongest Pokemon. Until then, Ash is beyond being "unbeatable".
