As of September 18th, 2019, the new Nintendo SNES wireless controller has been released. Although it is exclusively sold to Nintendo Online members. Here is a link to where it is available for purchase.
After the most recent Nintendo Direct, we got an awesome rundown of the new SNES library launch that was coming to all online subscribers. Although, while these games came out the following day, we were also shown a brief example of a wireless SNES controller, with no release date! (how cruel)
While it seems that the controller has already sold out, Nintendo will allow you to go ahead and complete a new order. This way you will be one of the first people to receive one when they come back out with another wave.
Although some gamers may be less than enthused seeing as this controller is another possible slap in the face to those who bought the SNES Classic. If this is you, one encouraging thought I offer is that the Switch SNES games are temporary. One day, whether tomorrow or five-years from now, they will no longer be offered online. So feel confident that you made a great investment in the Classic, as I am certainly still wanting to get my hands on one.
After a short couple of weeks Nintendo has finally released this glorious controller, and we are now officially able to complete the nostalgic experience when playing these video game gems. Time to play The Legend of Zelda: A Link To The Past, the way it was meant to be played!
