I bought the official sony bluetooth headset for $100 its wireless and connects through a usb port on my ps3 so will it work for ps4? I think it would be stupid for me to have to buy another headset eventhough this oe is supposed to be fully supported by sony since it is their product.
Not a bluetooth headset, no. But the launch firmware update will allow you to use a regular USB headset. However, the PS4 comes with a Mono chat headset. So, one will be provided.
