Yes. Obviously the high spec stuff won't be ported to Switch, as the current high spec stuff hasn't either with a few exceptions. A ton of Switch's third-party games are 7th Gen and older ports, as well as indies. Neither of those are technically demanding.
PS5 and Xbox Series X will affect the Switch, but I don't expect a huge Switch drop-off because of them. At least not right away.
