In an age where it's nigh impossible to keep a new product secret, the Nintendo Switch, previously known by its codename NX, was generally a known quantity. In a short video released by Nintendo, we can finally see this new hybrid console in action, coming March 2017.
The device itself is essentially a tablet, with a screen size of around 7 inches. On either side are the Joy-Con controllers and they have a fairly traditional layout. Unlike the Razer Edge, these controllers are naturally integrated with the Switch. Physical games will come on carts, and are inserted into the top via a covered port.
Whether you're on the go or at home, the controllers can slide off the device and be used wirelessly. They can still act as one controller this way, and there will even be a controller shell, the Joy-Con Grip, available for the Joy-Cons to slide into. Or, they can function independently for multiplayer games, kind of like a smaller Wii Remote. Wait, this is a tablet, isn't it? How will you hold it if you're using the controllers detached? POW, kickstand.
The Switch also doubles as Nintendo's new home console. Included is a dock with various ports that the tablet slides into. This dock covers the screen of the Switch, so this isn't like the Wii U. You won't have a game displaying on your TV and still interact with the screen on the tablet. You can then detach the Joy-Con controllers as previously mentioned, or use the new Pro Controller that Nintendo will also sell.
