Nintendo recently filed a patent for the Hinged Joy-Cons from the United States to make the controls more ergonomic. The original February 2018 document explains that this new form of control would work whether or not the Joy-Cons were connected.
The 54-page file, to which the LetsGoDigital site was accessed in its entirety, features images that demonstrate more flexible commands that differ from the current ones. See the photo gallery for the differences.
Launched in March 2017, the console early showed that it was a good bet from Nintendo, surpassing the number of sales by all other systems of the brand during its first 48 hours in the market.
And now it seems that Nintendo is trying to "improve" the Joy-Coins, after the controversy with controllers, which had some problems reported by customers. The company has been undergoing renovation, recently revealing a new console, this time cheaper and simpler, and then made some improvements to the standard edition of the system, optimizing the processor and battery for more autonomy. It remains to be seen whether this new Joy-Cons formulation will be effectively applied to future consoles.
