Well, the "multiple Switches per household" thing has come true in my household at least; my little brother got tired of having to share my Switch and me not letting him take it on the go, so he has just bought his own.
EB Games had a big discount with the Switch marked down to $400 AUD, so he took the plunge.
This is a guy who by the way has a gaming PC stronger than an Xbox One X.
I might get a second Switch just for Pokemon Sword and Shield.
Some days I just blow up.
