A Nintendo representative has confirmed to Kotaku that you’ll only be able to voice chat with select games. Games that will be supported include Assassin’s Creed 3 and Call of Duty: Black Ops 2. The Wii U GamePad includes a mic but you won’t be able to use it with in-game voice chat. Instead, you will need to purchase a headset from Turtle Beach or Mad Catz which will plug into the headphone jack. As you may already know, the Wii U Pro Controller doesn’t include a headphone port. You will have to use the headset on the Wii U GamePad, even if you want to play Black Ops 2 online with the Wii U Pro Controller.
“Wii U will have in-game chat functionality for select games, including, but not limited to, Call of Duty: Black Ops II, Assassin’s Creed III and Mass Effect 3. This feature will be supported by licensed stereo headsets that plug directly into the headphone port of the Game Pad. Licensed headsets are available from Turtle Beach and TRITTON.”
