Unfortunately, due to circumstances out of our control, the certification process for the PS3 patch and DLC has taken much longer than we expected. As a result, we have been forced to push back the release date for the PS3 version to 3/19.
The PC patch contains updates that will improve mods cooked for PS3, so we'll be taking advantage of this extra time to work with mod authors to make sure the best mods for UT3 are cooked with the latest patch.
