Let's try to get this thread back on track:
Hollow Knight sold well enough on Switch that the only console version announced for the follow up (Silksong) is the Switch.
Shovel Knight had the Switch as the 3rd best platform in April 2018 when they reached 2 million sales. https://yachtclubgames.com/2018/04/two-million-copies-of-shovel-knight-sold/
The Switch got to that position in 12 months, who knows where it stands now for that game. Also worth nothing that if we use src's line of thinking the Nintendo family is the clear winner with 55.8% of all Shovel Knight sales across Wii U, 3DS and Switch.
Signature goes here!
