In the past a console generation was 4-6 years.  Nintendo was right on time with the Switch.  The screwed up timing comes from Sony and Microsoft.  They are acting like a console generation is 7 years now, but no one is really buying Microsoft hardware right now.  I'm still not sure if Sony can get away with a 7 year generation for PS4 yet.  Sales are falling fast this year, and interesting games are drying up.  PS4 software was much better last year, and Sony skipped E3 showing they don't have much else planned for the PS4.

So Sony and Microsoft have created this hole in the gaming marketplace, and Switch just happens to have released at the perfect time to take advantage of this hole.  Most likely 2019-2022 will be total Switch domination.  There is very little competition for Switch from the current consoles and by the time PS5 and Scarlett release it will take them time to ramp up.  Switch is going to have most of the generation with almost no competition.

Most consumers vs Useing a number = everyone.

I just think its easier to market, and will show better results, without confuseing any consumers, if they use a normal nameing scheme.
Same with Xbox, the logical next name is Xbox Two (following the "one").

But if a company wants to do away with logic, and pick a stupid name..... hell its their company, their free to do so.
Just dont think it makes sense to do so.

They are competing, it's just that people want to turn a blind eye to anything below the layer of AAA third party support. Sony and Microsoft act quite oblivious to it too, hence why they are going ahead and will launch consoles that will likely cost $499. There are similarities to the seventh gen where Nintendo was written off and then won the generation with ease. The major difference this time around is that Switch is established as a strong console for single-player games, so there won't be a shortage of such content. There's now a lot of overlap in the game releases for Nintendo, PS and Xbox when the entirety of the software market is taken into account. Switch has an advantage due to its hybrid nature as people begin to realize that Switch allows them to finish more of the games they buy.

I wasn't talking about Switch vs. PS4, but overall. Nintendo sold the most consoles during each of the past two fiscal year and will sell the most during each of the following two fiscal years. This means that during the fiscal year ending March 2021 Switch will outdo the PS4 and PS5 combined.

Yea, except they really aren't.  Do you honestly think people who chose the PS4 or XBO as their main console are going to not get one next gen in favor of the Switch?  A much less powerful console than they had the previous gen?  The answer is hell no.  Those people want an upgrade in power when selecting a new console.  Sure, they may choose Switch as a secondary console.  Of course, that still goes in favor of my argument of them not truly competing.  And next gen, we are going to see the support for Switch begin to drop, as well, as devs move on to MUCH more powerful HW and try to get the most out of it.  A AAA game is just not going to run on a Switch unless it is incredibly pared back to barely being the same game.  A simple resolution drop and/or drop in asset quality isn't going to solve the discrepancy in the CPUs/GPUs.  And the Switch being a hybrid isn't necessarily going to lead to people finishing more of their games.  Especially for many who never travel with it.

And I figured you were going to use some strange reasoning to try to make Nintendo #1.  Sony must have been doing great against Nintendo last gen, then, since we can combine PSP, PS3, and PS2 sales for those early years.  Still doesn't change the fact that Nintendo ended #1 that gen, just like Sony did this one.  Both in sales numbers and profit.
