As with all new software and tech, things progress.
What is the curren bluetooth version?
What version of Bluetooth will the ps4 have, and will that be backward compatable with previous versions?
The pluse headset is a RF dongle headset not Bluetooth, So as long as the USB driver and Firmware based encoding of Audio is still in the PS4 firmware the Pulse headset will still work.
The lack of Bluetooth support is why it needs a cable to connect to PS vita.
(Unlike the PX5 that has RF and BT mobile phone support and can pair to both the RF base station and BT phone at the same time. )
The PS4 Will be launching with a wired Voice chat Headset port built in to the DS4.
It will not be releasing with a Game audio headset, which the Pulse headset is...
Game audio headsets will still be required for night time family house play time.
Does anyone know if its possible that the Pulse Headset would work on the PS4 without the need for the dongle and just use the latest version of bluetooth?
I'm not saying this is comformation... but below is an image of the prize Sony is running at the moment and I hardly doubt they would include the headset just to be used as a stereo headset for the Vita.
