Nintendo will introduce new Wii U accessories as the console matures. One possible accessory is an advanced version of the Wii vitality sensor, and a new steering wheel “cradle” for the tablet controller. The vitality sensor is still in development at Nintendo, and the Wii U might be the perfect console for the new accessory.
Third party manufacturers will reveal their lineups of Wii U accessories once the final specs have been released by Nintendo. The manufacturers will like bring everything from chargers, to docking stations, to gun attachments, and much more. It’s also expected that a lot of the current third party Wii accessories will work with the Wii U through firmware and software updates. Makers like Rocketfish, Mad Catz, and Nyko are all expected to have Wii U accessories such as their versions of the ready once the new console launches in November 2012.
Nyko's first line of Wii U accessories is all focused on the problem of the GamePad's short battery life. The company has revealed five different devices to help extend playtime, from battery packs to power cables.
The UBoost is the traditional add-on battery pack, attaching to the back of the GamePad to extend playtime "upwards of 10 hours." It has a built-in kickstand, replacing the dock as a stand – though the dock still charges the GamePad with the device plugged in. The Charge Base Pro charges two Pro Controllers simultaneously.
Other accessories include replacement charging stands and AC adapters for GamePads, and the Charge Link, a handy USB charging cable. You can use the Wii U (or any other powered USB device) to charge the Wii U's controller. What a novel idea!
The Charge Link cable is out now for $15, while everything else is due sometime this year.
As mentioned above, if you want to play multiplayer games then you are going to need a few Wiimotes and Nunchuks. The Wii versions are compatible with the Wii U, but Nintendo is taking the opportunity to rebrand its Wii peripherals and offer them as true Wii U accessories.
