Update: This rumor has been confirmed as true, with the tipster's screens originating from the PlayStation Web site itself (see HERE, HERE and HERE).
There has been a lot of buzz circulating around the next PS3 Firmware update, presumably version 3.10, which is what developers currently have.
Last month, Cross-Game Voice Chat was inadvertently confirmed to be included in it from a Naughty Dog developer.
Today, ScrawlFX.com (linked above) received some pictures from a tipster indicating that Facebook and Gamercard colors may also be included in the next PS3 Firmware update.
To quote: "Facebook integration, the ability to change your gamercard colors and more are coming to PlayStation 3, if these images from an anonymous tipster are to be believed.
The leaked images show the ability to manage your Facebook in your PlayStation Network account settings, changing the color of your PlayStation Network gamercard and a new, more sufficient way of looking through your photos."
