You'll get games and a lot of good ones from Nintendo on Switch. And a handful of good ones from 3rd parties, Japanese ones mainly.
That said, I think it's equally true that Switch represents in a lot of ways the end of the Nintendo home console.
No one is going to use this as their primary home console other than a very niche group of Nintendo hardcore. Not with the PS4/XB1 already available to be had for $250 (that price will become permanent next year).
If you think of it as the 3DS successor it's simply much, much easier to embrace it. It's a very nice upgrade for Nintendo's main audience -- the 80-85% of them that bought only a 3DS this generation while allowing Nintendo to somewhat appease the small remaining console niche they had left (14 million Wii U owners).
