Depends on if Nintendo ever felt the need to lower the price on the game and include the dlc with it(lol at that ever happening for first party). There's a strong chance that the only way to get everything is to just buy the dlc on top of the game. With dlc being a newer thing for Nintendo they may see no reason to make multiple versions of the game that have dlc included on the disc. This is also mainly done with games that sell millions anyway and having the game/dlc all on one disc is likely to be for a profit, HW on the other hand and how the WiiU is doing....will be lucky to break the million mark.
