1 million shipped in 20 days is good but it's nothing mind blowing that will make third-parties care about switch, and yes people buy nintendo consoles for mainly nintendo games, just look at how insane nintendo games are selling.
It certainly won't stop there. It can definitely go up to 3m LTD. And considering its production costs, it is bound to be more profitable than many other games.
And they're selling that well for a reason. They're great, desirable games. If third parties want in on the fun, they should also bring their A game.
