PSN Sign-In required for backing up save data, analog audio technically supported, but 3D Blu-rays are not.
Sony has posted the PS4 manual for all to peruse and within its pages are a few interesting notes. First, there are what looks like user-specific save files, which can only be moved when signed into PSN. Then there is analog audio, which can be transmitted from the controller's headset port. And finally, there is the 3D Blu-ray support, or lack thereof. 3D Blu-ray support seemed like a give-in, but according to the manual, 3D Blu-ray playback is specifically not supported.
Copy to USB Storage Device
You can copy saved data to a USB storage device that is connected to the PS4™ system. Saved data that you copy can be used as a backup, and you can copy saved data from the USB storage device to another PS4™ system and continue playing a game.
You can select for each game the saved data to copy.
To use this feature, you must sign in to PSN.
Copy to System Storage
You can copy saved data on a USB storage device to the PS4™ system. You can select for each game the saved data to copy.
You must be signed in with the same account used when you copied the saved data.
Analog audio output... through the controller.
Output to Headphones
You can set the audio that is output to the device such as a headset. You can output all audio, or output only chat audio.
Select [Sound and Screen] > [Audio Output Settings] > [Output to Headphones]. The default setting is [Chat Audio].
Then there is the list of specific supported and unsupported disc types.
Supported disc formats
BD-R/RE (BDAV, BDMV)
DVD-R/RW*2 (video mode, VR mode*3)
Playback of the following types of discs is not supported.
DVDs that have not been finalized
Here is the 3D section from the PS4 FAQ:
Will PS4 support any 3D content, including stereoscopic 3D games?
Technically, PS4 supports 3D gameplay at launch in North America, though no launch titles are currently 3D compatible.
It's reasonable to expect further comment from Sony on 3D Blu-ray support over the coming days. In the meantime, here's the specific page of the manual.
The manual contradicts the Engadget report that declared 3D Blu-ray support a certainty for the PS4 launch.
