During the Pokemon Direct, the release date for Pokemon Home was revealed.
Unfortunately, that was about it. Other than being a paid service, we still have very little information to go on.
From prior coverage we know the service will let you transfer Pokemon from Pokemon Let’s Go Pikachu, Pokemon Let’s Go Eevee, Pokemon Go, and Pokemon Bank to Pokemon Sword and Pokemon Shield. Though this is under the caveat that the Pokemon species must already be in those games (and the recently announced expansions). It was also stated the service would have some form of interactivity with the Pokemon stored.
More details are set to be announced before then, and we will keep you posted as we learn more.
Pokemon Home launches February 2020.
