Doubtful. For one, just making the actual cardboard device sounds like it can take like 2-3 hours for each one. So just putting together the cardboard last longer than many games made. Then add to the fact that this is something the kids will have made themselves and they will treasure/appreciate it more and think it is cooler.

It only requires 2 joycons. One attached to the visor and one in the back of the backpack.

The Visor one I assume tracks your rotational movement and so on and the character mimics that on screen. You know if you turn your body left or right, ect.

There is then strings attached to your legs and arms by just cardboard. These strings go back to the backpack and are attached to some sort of pully system that when you say thrust your right arm out, a piece with reflective tape on it moves up and then respectively back down when you retract your arm. That is what the joycon in the back of the backpack tracks. It uses its camera to read those reflective tape movements and then transfers that to screen. It knows that when the reflective tape moves up that you just punched with your right fist. It knows when the refelective tape for the left leg moves that means you stepped forward with that leg.

So no, no extra joycons, just a creative way to simulate having 5 joycons.

Yours truly is quoted in the Financial Times: "Nintendo adds nearly $1.4bn in value... with cardboard" https://t.co/MzUqAWg4BA via @FT

If you're into RPG games, then maybe good ol' Hiroshi Yamauchi had the answer:

Totally agree and posted the same sentiments earlier.

It doesnt matter. If Nintendo was able to get a 250 mio usberase in 7th gen, their goal needs to be to get that got or better again. No matter how, They are trying the Fusion concept currently, if it just sells 100 mio they would make ALOT less profit compare to the past which is bad.

Amiibo is quite a brilliant name. 

Ami = French for friend

bo = bot

---> Friend bot. 

So if the PS4 and Vita in total don't make the same sales as the PS3 and PSP in total, it's a flop?

Really really uninformed thing to say. Besides, they are still selling the 3DS, which still sells pretty good lol.

Yeah but it's Nintendo so if they want to sell you cardboard at the price of gold, people will pay and think they bought diamonds. So this is embarrassing indeed but not for Nintendo, they are the ones who will cash in on all their naive customers.

And I thought the Switch was weak from a point of view of processing power, now all those who say that such power is not what matters the most in video games are going to be very happy cause yeah, cardboard LOL.

You mean things for kids with interaction between a physical object and your game, like Wonderbook ?

or creative things like papercraft with Tearaway ?

(I'm just playful, I know papercraft in tearaway is not the main goal of the game unlike Labo.)

I'm a father with a young child, but I'm not excited by this (maybe even a little disapointed). Why pay € 400 (Kimishima said he thinks he's touching an audience that does not have the switch yet, or even doesn't play video games usually) to play with cardboard objects that I can do for free ? Certainly, I will not have the interaction with the video game as it is necessary for the piano or the house, but for games like fishing or being like a robot, I already do it very well by myself.
I can nevertheless understand their appeal when you already have the console and you are not very handy, otherwise no. There are much better options for much cheaper. I feel like it's Wii Music all over again but I could be wrong of course.

Well, currently I'm still waiting for more details (software part especially). Only time will tell wether Labo will meet the expectations. 

Wow.... 300+ posts after only a few hours. Nintendo Labo sure made an impression in the videogame community

I think some people are just overthinking about it. It´s clearly a product aimed at kids, Nintendo even didn´t build any hype over it . In their hand-on events to be promoted in New York and San Francisco, admissions are accepted only for parents with kids between 6-12 years old.

It´s definetely not a product for "gamers"... although I can see some grown-ups buying one or two of those kits as collectibles. And I can see many people showing-off their customized Labos just as many did with amiibos.

As a toy that combines an assemble cardboard kit with a video-game.... I think this concept is really interesting. I just don´t see it making a huge impact as Wii Sports did.
