The PS4 media remote is coming from PDP. The company has not revealed too much about the remote aside from the fact that it will be out this October for $30 (USD). You can, if you so desire, pre-order the remote right now from either Amazon or GameStop.
The officially licensed Universal Media Remote for PlayStation 4 gives you complete control of all PS4 media playback via Bluetooth. Easily control up to 4 devices-PS4, Set Top Box, TV, and Audio Receiver-and enjoy direct access to the PS4 Home and Power buttons without a controller. Enjoy a convenient and hassle-free way to navigate and control your PlayStation 4 system from your couch.
The remote will require two AAA batteries to use, which should last you about six months.
