During the Gearbox panel at PAX (Penny Arcade Expo) They gave a release date of September 28th for the fourth downloadable add on for Borderlands. Along with the new DLC for Borderlands they will also be releasing a patch to raise the level cap from 61 to 69, this will also effect those who did not purchase The Secret Armory of General Knoxx DLC raising their caps from 51 to 69 . Gearbox has not given a release date for the patch but they are aiming for one near that of the new DLC. Sounds like Gearbox had a fantastic panel at PAX this year. Setting a release date for this DLC, annoucning a raising of the level cap and showing off gameplay of the upcoming Duke Nukem Forever (Finally)!!
