Nintendo Switch owners need not worry about the next console, as it will be backwards compatible with the current console

Nintendo hasn’t announced its Switch successor yet, but we do know one thing for sure: it will be able to play current Switch games and have carryover for your Nintendo Switch Online services and account. The news was announced during Nintendo’s midyear policy briefing, with further information promised “at a later date.”

"At today's Corporate Management Policy Briefing, we announced that Nintendo Switch software will also be playable on the successor to Nintendo Switch," Nintendo posted in a social media update attributed to company president Shintaro Furukawa. "Nintendo Switch Online will be available on the successor to Nintendo Switch as well."
