patch for Battlefield 3 is coming soon. The PlayStation 3 is confirmed to get this new patch on March 27th with news of released information for the Xbox 360 and PC versions to be confirmed soon.
The new patch will add a very large number of tweaks and resolutions to balance issues. Perhaps one of the more interesting things is that the “Rent a Server” functionality will be added to both the Xbox 360 and PlayStation 3 console versions of Battlefield 3.
