Sony has filed a certification for a wireless Bluetooth adaptor. (You can see the registration here.) It’s possible that it will be related to the DualShock 4 and the – official – ability to use it on PCs.
According to DualShockers, this registration is related to a controller due to the code: its first half contains a Z letter. Remember, about a month ago, Sony registered a DualShock 4 model at the FCC with the CUH-ZCT2U codename. Yes, that also contains that letter.
Previously, Shuhei Yoshida has said that PlayStation 4 hardware support on the PC isn’t out of the question, because „the PlayStation 4 shares a lot of internals with PCs.”
As they previously have made Remote Play available on PC, a wireless adaptor would be the next logical step for Sony. If this is going to be related to the DualShock 4 in the end, we wonder when it will be available, and what its price will be.
