People always forget the cross gen period. By the time next gen only games kick into proper gear, the switch 2 will be out with more powerful and modern hardware which should continue the third party games support. Especially now that a console like the Series S exists and Nvidia having a technology like DLSS up their sleeve.
It's just a matter of whether or not Nintendo will make an odd decision but I remain hopeful.
