We plan to release this update for all platforms (Playstation 3, Xbox 360, and PC). No release date is set at this time. Once an ETA is established, it will be posted here.
In addition to the security updates, this patch will also address a small geo exploit on the map Fuel, which players exploited in order to get inside a rock on the outskirts of the map.
The upcoming patch for "fight hackers' has just been send to SONY for verification. NO ETA at this time but i guess between 3-7 days the Patch will go LIVE.
