The Wii U may be put to rest sooner than you think if this is true. Some Nikkei sources claim that Nintendo is stopping production of the struggling home console at the end of 2016, and that they are already discontinuing some accessories for the console.
There is no official word from Nintendo about this yet, but if true, this could be seen as preparation for the NX system that will be coming next.
Now that doesn’t mean that the NX will ship this year, even if this is all true. Stopping production doesn’t mean that Nintendo is stopping sales after all. It might keep the Wii U around for a while longer just to clear their remaining stock.
A production shutdown late this year makes sense. The Wii U was supposed to sell like hot cakes thanks to the success of the Wii and its motion controls, but its unique touchscreen-equipped gamepad and minimal performance boost led some developers to skip the platform and these things hurt the system. Nintendo would want to both cut its losses and show that the NX is coming soon, so this news could be right on the money. I really wouldn’t expect anything else.
