No screehshots yet, but we've got a crate-load of specs for the new PS3 OS which will be always available, like the XBox 360 Dashboard.
Multi-User Voice Chat across all games, even outside of the games own UI
- Multi-User Video Chat across all games, even outside of the games own UI
- Notifications and messaging to be sent between users regardless of the games they are playing
The rest of the info is pretty esoteric, but the OS wil always be available for housekeeping and memory protection and it should also stream and download content as well has handle on-the-fly DRM for games and media.
