PS4 system software update 1.70:
The major updates packed into 1.70 include the ability to save captures to a USB drive, the option to turn off HDCP protection for games, HD gameplay live streaming and archiving for Twitch and Ustream, tweaks to Twitch/Ustream/Sharing interfaces, SHAREfactory video editing, and apparently a few other changes and improvements.
It doesn't look like the DualShock 4 lightbar dimming will make it in there, or friend online notifications, or mp3 playback. But we'll see.
