Forum:Borderlands Goty

The wiki and several other sites say that a strategy guide for a goty edition was spotted on gamestop but its gone, they must have removed it. Does this mean that theres no more dlc if the goty is real? I've only owned 2 goty games, both elder scrolls, I don't know about other games or developers but doesn't goty mean the end of that game and having all dlc. The wiki said that the president of take two said there would be at least one more dlc. Does this mean no more dlc or will there be a dlc released soon for those that have the game now and the goty will have all 4?
