Hardware what could be the use of that button?

[TehCupcakes]

Hard to say what its function would be when attached to the main controller. Although I think it's pretty safe to assume they wanted the "left joy-con" and "right joy-con" to have the same number of buttons, given the local multiplayer feature. I'd also say it's safe to assume that each side needs a button which can more-or-less function as a "start" button. Traditionally this has been +, so I expect Nintendo to stick with that trend and use + and -. That leaves really only one logical option, and that would be that it mirrors the home button functionality (when playing multiplayer with detached controllers, at least.)

I'm guessing it is a game menu button. When in 2-player mode the +/- buttons become the game menu (or whatever the game decides to do with it) while the square button becomes a home button for the second player.

I doubt either controller has NFC. I think Nintendo would put the NFC on the console itself, and hjave the Joy-cons as cheap as possible. I suspect they don't even have motion controls or rumble.

Shouldn't there be a power button somewhere on the controller?

could it be the sync button, to link it, although i would expect thats what +&- would do... could be for a speaker... could be a lot, let's just wait , speculations won't help you know... before you can have one at home i'm sure you can test the idea somewhere... really this forum is floading with speculations lately...

It's likely the share button and perhaps home when used by itself. Though the Joy-Con grip having 2 sets of lights make me think it's more for battery life than player number in that mode. Or it is player number and the lights brightnesses differ depending on the battery charge of each one.

BTW other photos show that it could be a pass-through on the grip while the actual lights are on the controllers.

NFC wouldn't need a button for it.

Powerbutton?!

Self destruct button.

Self destruct button.

No, its not red and big enough for selfdestruction.

 

[xtheman]

Home button for when playing with 2 players or by yourself with one joycon is all i can think of.

The dummy console is just a Work in Progress.
They just forgot to paste the big red button in post production like they forgot to correctly clip the fake gameplay footage.

how about the horn function to blast an squeeq sound so loud you can hear it in the next city? i really don't care about it's function! stop please with floating this forum with such spam.

Early rumors pre-reveal said the controller would have a "share" button. They were right about the split D-pad, I see no reason why they'd be wrong about this. Nintendo might finally go more media-friendly with this console

Self destruct button.

that's in a bad spot too. casually playing a game with the d-pad the next minute on the screen

shit i pushed the wrong button!

Given the protable/console nature of this, it would need 2 NFC spots, one on the reader, one on the controller.

Also, the NFC reader is literally just a wire. Less than a yen extra expense

 

[Futurdreamz]

The wire needs a chip to run it...

The controller will already have a wireless communication chip, that'll do.

People are still asking this dumb question? It is a Sync button...*insert EPIC DUH here* how else would you sync the controllers to the unit? Even the Pro version of the switch controller has the button.
