It appears Nin­ten­do is work­ing on anoth­er con­troller for the Switch, but details on its periph­er­als are almost non-exis­tent. The new con­troller was unveiled in an FCC fil­ing (spot­ted by VGC) from Nin­ten­do, that’s sim­ply titles “game controller.”

The only real infor­ma­tion that can be found in this fil­ing is that the con­troller will be wire­less, and con­nect to the Switch with Blue­tooth. The man­u­al, block dia­gram, and schemat­ics have been made con­fi­den­tial at the request of Nintendo.

In a let­ter to the FCC, a rep­re­sen­ta­tive for the com­pa­ny request­ed con­fi­den­tial­i­ty for the parts, writ­ing, “The appli­ca­tion con­tains tech­ni­cal infor­ma­tion which we deem to be trade secrets and pro­pri­etary. If made pub­lic, the infor­ma­tion might be used to the dis­ad­van­tage of the appli­cant in the marketplace.”

How­ev­er, the fil­ing also show that these doc­u­ments will be released to the pub­lic in exact­ly six months, so an announce­ment might be com­ing in the next year.

It’s unlike­ly this new con­troller will replace Nin­ten­do’s Joy-Cons, and instead be anoth­er wire­less alter­na­tive for the prob­lem­at­ic Joy-Con con­trollers. It’s been four years since the Joy-Cons were released, with stick drift still being a major issue to this day. Nin­ten­do’s pres­i­dent Shuntaro Furukawa apol­o­gized for the defect last year.
