This is somewhat reassuring, the leaks are pushing the Switch 2 as nothing more than a spec bump with a larger screen instead than a new device, which isn't what Nintendo should be working on to succeed the Switch.
Nintendo has denied any connection to a mockup of its rumored Switch 2 console showcased at CES 2025, calling it "unofficial" and distancing itself from leaked images and videos. An official announcement about the Switch's successor is expected by the end of the fiscal year, concluding March 31, 2025.
