You shouldn't have "got" anything. It doesn't matter when or how a developer develops content. Even if that content was finished when the game released (which it obviously wasn't), it's their game and they can sell it however they want. Those leather seats in your new car were designed along with the car. Why do they cost more then? Aren't you entitled to them since you bought the car? It's obvious that developers begin working on DLC before the game releases. That's because different departments are done with a project at different times. Why lay people off when the game goes gold instead of putting them to work on DLC? That doesn't mean it was "well let's take all this content that has nothing to do with the vase story out of the game and sell it as DLC." That content was always intended as additional content. It in no way was ever part of the base game.
