"A source close to Rockstar has confirmed to us that the development studio will be releasing two additional dowloadable content packs for Grand Theft Auto IV, that both of them will be coming to the Playstation 3 and Xbox 360, and that one of them will focus on the Irish families that Nico helped in the first episode. This confirms earlier rumors circulating around E3 that Rockstar was planning to release a DLC episode called Blood and a Four Leaf Clover."
