I don't think they'll be able to do that. Under this ruling you have the right to re-sell everything you buy, including dlc. So they can have day one dlc but they'll have to enable you to sell it on if you want to. It's also possible that they'll have to let you sell on your bonus content codes along with the game, depending on whether or not the bonus content codes are considered part of the first purchase. Personally, I hope we see more of the GoG DRM free approach to selling games.
