A tweet from LYGO International has revealed that they are planning to launch a head set simultaneously with the Wii U. The Wii itself had an optional voice chat feature called the wii speak. The wii speak allowed people to talk with each other over the internet but since it was not a head set it didn’t sit well with many gamers. But now you’ll be able to be yelled at by angry gamers on Wii U just as you are on Xbox Live and PSN. At least now when we play any games that have online multiplayer we will be be able to have a private, personal sort of communication with people right from the get go.
