its true, for now this is xbox exclusive DLC “The Lost and the Damned”. there will be a total of 2 episodes (new storyline that intertwines with the original story clocking at 15-20 hrs of additional game time). microsoft struck a deal with rockstar, paid ridiculous amounts of $ and voila. however no one knows if this is exlusive forever to microsoft or exclusive for, say, 12 months. regardless, DLC will be coming to PS3 at some point as well. whether it'll be the EXACT same as what xbox gets, no one knows right now.
