The Switch is barely ahead of the PS3 generation. It's a .5 ahead of that generation so it's gonna be 1.5 generation behind the ps5

"it's going to hit 60 million easy..."

God you are delusional. Nintendo will be lucky if the Switch sells half of that.

Not for the reasons you think, which are all wrong.

No, it really doesn't. There's a thing called "blue ocean strategy." You should learn about it, you might discover that it's a very interesting subject. Basically instead of competing for a shared market, you create your own market. Nintendo exists in the "Nintendo market." People buy Nintendo consoles to play Nintendo games. Nintendo can support any piece of hardware entirely on their own. 3rd party titles are just the icing on the cake. No Nintendo console, ever, has been dependent upon 3rd party titles in the way that Sony and Microsoft have been throughout their entire time in the gaming industry.

There's more cross over between Apple and Nintendo products than there is between Sony / MS and Nintendo. And that's a big part of the reason why Nintendo is making spin off titles for the mobile market. Of course you do know that Sony is also making mobile titles? Right? Meanwhile Xbox and PlayStation are two halves of the same coin, and both are competing with the ever growing and increasingly accessible PC market. Eventually both brands will evolve into a Netflix style gaming service, but that's many years down the road. Their best content will eventually be available on everything from tablets, PC and even smart TVs. No more boxes for the kiddies to argue about.

Of course some companies don't believe in the "blue ocean" philosophy. A former head of Sony once said that he saw every form of entertainment as competition for his brand. This included things like reading a book or riding your bike. I personally believe that's an outdated philosophy and many people in the business world agree with me.
