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.
