Wii U Wiimotes have external sync button
While the Wii U will be compatible with previous Wii accessories and controllers, Nintendo will offer Wii U branded Wiimotes.
But Nintendo didn’t just take some old Wiimotes and slap a “Wii U” logo on them. The new motion controllers are actually improved in many ways.
Besides featuring built-in Motion Plus technology, the Wii U branded Wiimotes will have an external sync button. In the older controllers, players had to remove the battery cover in order to sync the controller with the console. The sync button is now conveniently located under the controller.
The Wii U console itself will feature an external sync button at the front of the console, to make everything easier for players.
Nintendo will launch the console with a slew of first party accessories, from Wiimotes and Nun-chuck controllers, to Pro controllers, console and controller stands, and even a screen protector for the GamePad.
