The PlayStation 3 and Xbox 360 editions of Borderlands hit North America on October 20 and Europe on October 23. The PC version follows a week later--October 26 in North America, October 30 in Europe--due to optimization. In its mailing, Gearbox noted that the console versions had "already gone off to the presses" while the PC edition was just "wrapped up."

On the plus side, various shops are currently offering Borderlands PC for $45--$15 less than the console versions--provided you don't mind the wait and have a capable rig.
