Speculation has been surfacing whether Nintendo are working and developing a Nintendo 3DS headset for voice chat. The device is supposedly going to be launching sometime close to the debut of Heroes of Ruin.
Heroes of Ruin will then utilize the Nintendo 3DS headset for VOIP support. Again, this is just a rumor, so watch this space. If the news is confirmed, this will be great news for 3DS owners.
