It was just a theory back when they still talked about making more dlc and now it's been proven wrong. You never know how many people actually bought Dawnguard and have played through it. There's plenty of gamers that like those playstyles. Either way,now it's just to keep an eye on whatever new patches Bethesda comes out with for Skyrim and see what they add.
