A recent Nintendo FCC filing once again resurrected hopes for a reveal of the Nintendo Switch's successor, but the hardware has turned out to be something vastly different. Nintendo is often tight-lipped when it comes to upcoming products, so it's not uncommon for concepts to first hit the public when people uncover new patents or similar reports. In this case, a wireless device from the company appeared in a Federal Communications Commission filing, but details like the lack of a battery and the lack of any reference to game consoles indicated that it wasn't what people had been waiting for.
