@DrJustice -- The reason is that third party Wii U games have had their DLC dropped before. Of course, that was a decision made by spiteful publishers like EA/Ubisoft.
By this point it's looking more likely than ever that the Wii U version will have the post-launch updates on the disc, and maybe some of the free DLC too. It seems sensible that SMS would pack in whatever is finished and ready by the time it goes gold...however many months from now that will be. Around my birthday (September)? In time for the holidays? Or will the new Zelda game show up first (2016)?
