UPDATE 26/9/24: A fresh deep dive into Nintendo’s mysterious new wireless gadget has offered up more clues as to what it might be used for.
Tech channel Remote Play Gaming has published analysis by a wireless industry expert who takes a look at the documentation provided by Nintendo for the device. Most interesting are the tests that have been done to approve the gizmo’s wireless transmitter for use close to the body.
The results here suggest Nintendo’s under-wraps creation is some kind of body sensor designed to communicate with a secondary device (and worn on or close to the body itself, rather than mounted on someone’s head). It sounds a lot like a movement-tracking accessory – though again, as below, there’s nothing yet to specifically link it with Switch 2.
That is the gist, but for more granular detail, the video below is worth a watch – as the wait for more answers continues:
