First years are always slow and I don't imagine Switch will hit its stride until Japanese devs will start abandoning 3DS & Vita (almost) completely in the next 1-2 years and move their products to Switch. Until then, I imagine Nintendo's offerings + some sparse 3rd party support on the level of Bomberman, Lego games and ports like Disgaea 5 & I Am Setsuna + a few rare bigger 3rd party games like that new SQEX JRPG + indies are most of what we'll get in the next 1-1,5 years.
I'm personally pretty happy with what 2017 holds for Switch (if there are no delays). I'll worry about 2018 & beyond when we get closer to 2018. Although a bit sparse, BOTW, Splatoon 2, Mario Kart 8 Deluxe, Xenoblade 2 & Super Mario Odyssey are plenty to keep me happy for this year as far as the desire for bigger, meatier experiences go and stuff like Voez & Fast RMX will be good smaller digital releases to play occasionally.
