Today during the Nintendo Direct Nintendo announced it will be releasing special wireless NES controllers for the Nintendo Switch, so users can play classic NES games the original way. More details have since come out and revealed that the NES controllers for Switch will only be available to players who subscribe to the Nintendo Switch online service.
The Nintendo Switch Online Special Offers website lists the NES Switch Controllers as being "Exclusively for Nintendo Switch Online members." This is part of the special offers Nintendo hinted at during its Nintendo Direct today.
According to the web page the controllers, which come in a set of two, will be available for $59.99 and will begin shipping out in December 2018. It also says each set will be limited one per Nintendo Account with paid Switch Online subscription, i.e. one per customer.
A lot of online subscription services offer special discounts or offers as part of its service, but Nintendo appears to be making its Switch Online service more valuable by offering exclusive merchandise through its program. How well this goes over with customers remains to be seen, but as it stands the only way to get the NES controller is by signing up for a Switch Online membership.
