WiiSpeak

WiiSpeak is placed on top of the Sensor Bar and acts as a microphone for not just one person, but the whole room. It will be sold apart from Animal Crossing: City Folk at an MSRP of $29.99]] WiiSpeak is a new accessory that will be compatible with games like Animal Crossing: City Folk and The Conduit. WiiSpeak will let players talk with friends they have registered via Nintendo Wi-Fi Connection.

Unlike Xbox Live Headsets, which only let the players wearing headsets speak and hear, WiiSpeak lets the whole room talk and listen to their friends, so it won't just be Person to Person but Room to Room.

WiiSpeak will probably also be compatible with upcoming games, but it is still unknown which games.
