So we're adding the cost of upto 4 wireless headsets for ARMS and 8 wireless headsets for Just Dance. Do you see how silly your 'solution' is when you take into account motion control, price, simplicity, local multiplayer? |
You're right. That sure is more expensive than 4/8 cell phones. Yup.
Microphone array then? Worked plenty fine on Wii and Wii U. They can offer multiple voice chat options, including the phone app. It doesn't have to be just one.
