Nintendo’s press coverage is on the move, currently they’ve demonstrated Wii Speak which will allow voice chat on your Nintendo Wii console. Although the Xbox 360 has had voice chat since its day one release, Nintendo is bringing it in a new unique way: community chat.
Basically, the device which will go on top of the Wii sensor bar will allow everyone in the room to talk to everyone in the room on another Wii. Where you need a headset on the Xbox 360 and PlayStation 3 this will give the entire room a chance to chat along.
Having a speaker phone style behavior is neat, but what about when everyone is asleep and you want to play a network game with a buddy? Will the device pickup a whisper across the room? Perhaps a speaker attachment will be announced later, but for now… you’re going to be conference calling with everyone in the game room.
