Nintendo gave a quick recap of their new online service during today's Nintendo Direct. While most of the information was old, Nintendo revealed some brand new NES-Style controllers for the system that will be compatible with the classic NES titles available through the service.
The new controllers can connect wirelessly and are compatible with the Switch's charging dock, much like the joy-cons. The controllers will be available in a bundle for $59.99 on September 18th when the Switch's online service officially launches.
