Sure, but they usually end up like this

Not sure what's so weird about all of them using the same Switch colours. I mean, they are super rich players, it could very well happen that one of them told their manager (or whoever buys stuff for them if they need something) to buy 20 Switch consoles for the team. Or that the club bought them for the flights and whoever the guy was to buy these consoles just put 20 consoles in the Amazon basket or whatever without thinking "ohh, I have to choose different colours"

Or maybe a player (or their manager) asked Nintendo to send them 10 consoles and Nintendo simply did that. these people can get a lot of stuff for free even when it's sold out and often before release, doesn't mean they are paid for it every single time. It's enough for companies to know there might be a chance they will mention it.

And even if it's a paid ad, where exactly is the problem? People talk about it, not much else we need to know. 

Under the logic that it's only Wii U owners buying the platform the sales would represent the Wii U's sales pattern as it goes in alligned weekly sales NS has already overtaken Wii U, the small console market in Japan would not give NS that rate of sales given the market's state in modern times it's more likely the case that 3DS and Vita owners are among the buyers migrating over because that's where all the future portable games will be. Even other console owners who didn't buy the Wii U would not give that rate as it would be more around the PS4's rate, Wii U in its prime was at like half the PS4's rate. The Console market simply isn't big enough to give NS that rate of sale alone week in week out.

Your PS2 example is badly flawed comparing one home console to another when we're looking at a device that is a hybrid which succeeds portables and a console look at your own example what relevancy does it have other than saying PS2 sold more than PS1, all PS2 owners would be console owners so how is that relevant in arguing about portable owners buy NS.

MK8D is #1, and Neon Switch is #2 on Amazon Spain.

I'm positive interruptor means switch as the button for turning on and off the lights since it's the same as in Italian, good ol' Google Translate still failing strong

Paid or not, is still advertisement :p
