The only real issue I have with this is that downloadable content won't be "extra". Not financially to the producers of the game. It's going to be content that was planned to be included either in the original release version or in the extended downloads later. It's money making and that's all it is. If they are actually developing stuff after the fact based on how well they liked their game and wanting to add longevity to it, they generally begin work on an expansion pack, and even those are planned towards the end of the development cycle for the original.
