The President of The Pokemon Company, Tsunekazu Ishihara announced that Pokemon Home will allow trainers to transfer their Pokemon onto their Nintendo Switch.
In the Pokemon Direct, it was also said that this service, Pokemon Home, will be a paid service, so if you decide to use it you might probably need to pay a fee every month or year. It is kind of similar to Pokemon Bank.
