Once upon a time, I thought that Nintendo was going to beat the Xbox 360 and PS3 out in the voice chat department by making their own earpiece headset.
Anyway, recently I realized that the Wii Speak peripheral isn't going to be very effective for voice chat in a high-action (see: loud) game such as Call of Duty 20XX. Furthermore, that Nintendo could realize they don't NEED to make a branded earpiece and simply do the smart thing by saying "We use bluetooth for the Wii remotes! Let's just let the player use any ordinary bluetooth earpiece!"
Yeah, that'll happen.
