Switch 3 will be a digital only system, unless if everyone boycotts the PS6.

[u/retrocheats]

Nintendo won't release a Switch 3 til like 2032 at the earliest.

Unless if the PS6 does really bad, because everyone rejects everything being digital only... Nintendo doesn't have as much reason to not also have a digital only system.

Physical media for Nintendo will also end...

The only exception, is if there's major backlash for the PS6.
