Yes, sometime before the release of The Walking Dead Season 2 on DVD and Blu-Ray in august. JB-HIFI (a store) released The Walking Dead Season 2 in Australia before the official release date. On the DVD from JB-HIFI, it only contains 13 episodes of Season 2, no special features or the scene where Shane is running from Walkers. They might have downloaded it and burn it on a DVD and released it.
PLEASE RESPOND ABOUT IT!
