1up - When they are released for Wii U this fall, you'll be able to voice chat with other players in Call of Duty: Black Ops 2, Assassin's Creed III, and Mass Effect 3. This is no newsflash; voice chat has long been a staple of online multiplayer games, though you could be forgiven for wondering how it will work on Wii U. After all, as Kotaku notes, we've yet to actually see a Wii U headset of any sort. And, for that matter, we've yet to hear much about Wii U's online setup. As it turns out, there's a reason for some of that.
