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.
Kind of hoping the slightly more powerful switch rumor is true, caue then would become a dual household too. Some games, I want to play with girlfriend like Stardew Valley, yet she don't have a switch. Hardly want to purchase a whole new switch for some co-op play. But if a new switch comes out that makes say loading slightly faster and no lag in BotW and others, then I would purchase that and have to systems then.
