He has returned.
We had truth vs ideals in the bw games but the anime failed to use that and we got an Ash reset instead.
Part of the reason why the unova reset was likely done in the way it was, was due to the fact that the first 2 BW games were cut off from the rest of the series, outside of the dream world you couldn't use older pokemon until you completed the main story, and they likely wanted to reflect that, but they went too far with it by "resetting" Pikachu in a bad way, especially after coming off the sinnoh league.
The fact that these games are open world though, that really makes me think we'll be continuing the world tour, at least with Ash should he still be around.
