So I wondered if anyone had seen any further information on this. To the best of my understanding at the moment the PS4 will only have HDMI output facility, but that will be copyright protected to the same degree that it currently is on the PS3. Therefore making game capturing impossible. Now I know that they have the share function attatched the the controller which will give you some form of game uploading, but if the above is correct then any PS4 users can kiss goodbye to any commentary, montage or anything else that would require a PVR & editing program software.
I didn't think that Sony would've done this but they've not said anything to the contrary and XBOX has been quite the opposite in saying that it will be supported. So i'm kinda concerned that their silence is saying all it needs to.
