Thats a point, not all Switch curent all future owners are not Nintendo owners also.

Playstation does a good job, but only for Sony fans?

Statements like these are ridiculous. Wii, DS and 3DS all sold more than 40 millions. If you choose that these all are Nintendo fans, than there are more than 40M. If you choose they are not, Nintendo can do a good job outside the Nintendo fanbase. Looking alone at this forum with a lot of people saying Switch is the first Nintendo system they got since <Gamecube/N64/SNES>, I tend to think this sells outside the core Nintendo fanbase. But whatever, no console sales ever fell completely from a cliff. They petered out. With the current momentum Switch will probably sail past 40M.

Ok, I should have specified the demarcation of my years (done in bold). It's the same thing when we compare consoles sales with launch aligned.

Yes it's an exception, but this exception already applied on 2 devices of 8th gen. I will wait until March 2019 to see if the Switch is also a victim of this exception (but with a larger sales volume). This may seem implausible, but nevertheless not impossible.

Agreed. But Pillertriller suggested Nintendo only sells to Nintendo fans.

Actually I think, if you purchase and like a console of Nintendo, you're probably a Nintendo fan. Even if it is your first one, so you're a freshly converted Nintendo fan. Therefore the number of fans is volatile.

Agreed, implausible, but not completely impossible.

Not sure about current. Since it was sold out and one needed to "fight" a little for the console and usually early adopters are more of the core. But anyway there is zero evidence that Switch will sell only to core Nintendo.

I'll probably buy one in the next couple years to play with my child that is entering the phase of gaming and already love to see Super Mario on Youtube.

That can be true, Nintendo games tend to be very enjoyable so someone playing for the first time may become a fan =]

Do you really think everbody of the owners of those 70 million 3ds users are hardcore fans? Same goes for PS4 maybe like 20% are real Hardcore fans of Playstation. But a PS4 is just much more appealing console in every way for someone who isnt a kid who wants a console to play games, besides the portability that switch offers.

A question to you : Why did the Wii U only sold 13 millions?

This has aged badly.

To hold the current standing of the poll:

I said over 30m back in 2017, but now I think the PS4 will win by anywhere from 15m-20m.

I think ya prediction of 30M is kinda solid, why change it?

Imho, switch isn't going to pass 100M, it will match 90M (maybe a little more). Momentum is good right now, but in the end sales will fall harshly, like Wii, and it will end a bit ahead of 3DS. That said, ps4 will most likely die close to 120M, so yeah, 25M-30M in favor of ps4 is a good guess.

Just look at 3DS, switch sales are not going to beat it by much, and than add that new consoles are coming and mobile gaming is evolving faster than ever! (Looking at you 5G gaming) switch not surpassing 100M, sales will drop hard in 2 or 3 years.
