Some people lost their trust with Nintendo after the WiiU, because of bad support (porting some of the WiiU's only good games to other systems [like the 3DS or Switch] or because the system did not get 3rd party support that it needed). 

However from what we've seen, the Nintendo Switch is a hybrid console that will be Nintendo's main console & handheld system for the next few years, so they are focusing all of their game development on 1 system instead of 2 systems!

With the Switch there can not be any issues of:

-Animal Crossing on the 3DS but not the WiiU

-3 Fire Emblem games on 3DS but not WiiU

-Other games that were on 3DS but not WiiU / vice-versa

And now we can (maybe) see with the Switch:

-Another console monster hunter

-Mainline Console Pokemon game

-No abandoning 1st party support (like the Wiiu)

Nintendo can now focus all their first party support on 1 console! Something that hasn't been done since 1988!

And, now you don't have to own 2 different Nintendo systems (console & handheld) to get all of the Nintendo exclusives. With the Nintendo Switch all the games are on 1 system, they can't abandon support.

It just me pointing out some stuff about the Switch that I haven't seen other people talk about.

Well they are still making games for mobile, so I don't know...

This will be Nintendo's only platform moving forward instead of being split between two platforms... It better be.

Mobile games don't take alot of development time and Nintendo said they plan to release just 2-3 mobile games a year

Well, I mean, sure, I agree, but they should be able to give support to the Switch without commiting suicide in the handheld market.

Its gonna invariably replace the 3ds, but even tho The Switch is a portable console it has the price of a home console with home-console priced games as well.  So - I believe - the idea that the 3ds fanbase is gonna simply... Switch (wink) to the Switch is a bit too much hopeful thinking. 

Switch will be well supported by Nintendo's 1st party, and that's why I think Kimishima is so smug right now. He knows that Nintendo, united, can really churn out tons of great content on the Switch and I think we'll see the floodgates open in E3 2017.

Because consoles can't drop in price or get cheaper revisions? 

So you want them to release a weaker handheld for a cheaper price? But a weaker handheld wouldn't last as long as a more powerful handheld as it would be outdated sooner. 

I absolutely have no idea what you are talking about. I simply said that supporting one console shouldn't mean to stop supporting your other console - which is the point the OP makes in this post with the comparison of the WiiU with the 3ds support.  Whatever happens during the lifetime of a console is besides my point.
