As explained in Nintendo’s press release, the Switch will feature multiple ways to play with the controllers, which allows you to adapt to your gaming style. The detachable controllers, called “Joy-Con,” let you play connected to the display, or remove them to play with one controller in each hand—similar to a Wii Remote + Nunchuk. While we have no word yet on whether the Switch will support motion capture, it should be noted that the Joy-Con each have a joystick, a traditional 4-button set, top button, and back trigger button.
Additionally, these miniature controllers can be slipped into a Joy-Con Grip accessory to emulate a more traditional controller experience, or you can purchase what Nintendo is calling an optional “Nintendo Switch Pro Controller,” which appears to closely resemble the Pro Controller for Wii U. Finally, the Joy-Con can be used for multiplayer action, with multiple people each using a Joy-Con to play a game together on single or multiple Nintendo Switch consoles. The Joy-Con may be the first Nintendo product to lack a true D-pad, although the Pro Controller does have one. While Xbox and PlayStation both offer traditional-style wireless controllers, they have nothing like the Joy-Con’s adaptability.
UPDATE: Ubisoft has just announced they are developing Just Dance 2017 for the Nintendo Switch, which essentially confirms some sort of motion-capture capabilities for the new console.
