That is true, while games like Labo would of course be possible with accessories on other platforms they would be more expensive and less successful. 

They made ~$250m from that online service they don't make a ton of money from.

In a single year.

At $20 instead of the standard $60. 

Hmmm, do you have a source for that? The highest number we've had released as far as I can tell is 10m current subscribers as of July. Which would be $200 Million a year, but that's best case scenario as it assumes all 10m will subscribe for an entire year, assumes all of them are paying (I got 1 year free with Amazon Prime, they also gave away subscriptions with some games.) and assumes none of them are using the $35 Family Pass that works for up to 8 friends.

So I'm not sure how they could make $250m in a year when the highest number of subscribers is 10m and a year ago they had 8m.

Regardless that estimated $200m (or $250m figure if that's correct) is still a tiny fraction of the best case scenario $2.3 Billion PS+ makes in a single year (38.8m @$60). So my point about Nintendo making far far less money from console services/third parties than MS/Sony still stands.

We also don't have to assume that releasing their games on other platforms would completely destroy their hardware sales. So they may not lose all of that $250m. I think they could generate more profit from releasing there games on multiple platforms, but really it's something that has too many factors to forsee.

While it could be possible, I don't think Nintendo would have the type of freedom to experiment like that while being under other platforms (i.e., Sony, Microsoft, etc.). Do you think they would be allowed to create something like Labo, Ring Fit, Wii Fit, Wii Sports, etc. under other platforms? Or do you think they'll just be stuck with Smash, Pokemon, Mario, and Zelda, with a few Kirby games?

Would they be allowed? Yeah absolutely. Platform holders don't stop you from releasing/making accessories for their consoles. There's been all sorts like UDraw tablets and Drumkits etc. They wouldn't be stopped from making them, but games like Labo probably wouldn't fair very well outside of the Switch.

I think really what it all depends on is how much more money they could make selling there games on PC and other platforms, and how many of those sales would be actual new sales rather than just sales transferring from console to PC. Though they could always just do a 2 year delay... and then people may even double dip, buying there games on Switch and then buying them on PC 2 years later... xD

I know I'd double dip on Odyssey and Mario Kart if they came to PC.

If they ported Odyssey, BOTW and Mario Kart to steam this year I'm sure they'd gross anywhere from $1-$2 billion. That's a hefty paycheck.

No recent source just 10m in July and a rough calculation accounting for holidays.

Regardless, it's pretty much pure profit compared with PC ports.

Sony's $2.3b would likely only be $770m if they charged $20 instead of $60. And only $385m if they were still on the 50m userbase Nintendo is.

Zorg/Rol/Kin Mao have pretty much said everything I was going to say on this, but  I'll add that since Nintendo are by far the most reliant of the Big Three on first party exclusives to perpetuate their hardware ecosystem, I'd say that gives them the least reason of the three to go multiplat.

As most of their games in some way are a union of hardware and software, Nintendo as a third party would probably make sucky games. And we already know they would take the path of mobile dev with microtransactions, this is what they do outside of Switch.

Honestly, I actually prefer Nintendo's hardware to Sony's and Microsoft's.

The latest graphics aren't a big draw for me, I like that they try interesting new things, and I like stuff like motion controls, IR, and a split controller.

The internal hardware of the Switch could have been better though. I.E. Pascal instead of Maxwell for a 50% increase in performance at the same powerlevel, I assume Nintendo just got a really good deal.
For GPU capability in a tablet/phone form factor, Tegra was the best option at the time, no doubt. (Although other chipsets are more performant now.)

The joycons I couldn't care much for... But the concept of them is awesome and novel... And allows for split screen multiplayer even in public without having to carry a heap of accessories. - However I prefer the Pro controller to be honest where possible, especially for shooters like Overwatch, but the Joycons were fine for something like Links Awakening.

The dock itself is a good idea that Nintendo could have taken further, but it is what it is.

Not a fan of motion controls though, usually it is the first thing I disable. Haha
