Exactly. I'm not entirely sure about worldwide, but 2020 should be the Switch's peak year in Japan due to Pokemon+Switch Lite momentum going strong into the year and Animal Crossing New Horizons not long afterwards + most 3rd party Japanese developers should start really showing their support for the system.
Saying Switch is dominating Japan is an understatement. The Switch has a good chance of selling as well, if not better than the 3DS did lifetime. The 3DS has sold 24.5 million units in Japan. The Switch just crossed 10 million sold in Japan.
