Wait. Seriously. Nintendo consoles usually have garbage 3rd party support in the beginning. They usually build up by the end of the 2nd year. I remember not really wanting any games on the wii 3rd party wise but when 2009 came there were too many to count. The same thing happened with the 3DS and the DS. Wii U was the opposite though. However that is a unique circumstance.
2019 will be when the 3rd party games come in full force. I recommend you clear your backlogs for 2019. Otherwise you will be playing Switch games well into the 10th generation.
