New Super Mario Bros. U patch to add Pro Controller support

Nintendo is working on a patch for New Super Mario Bros. U that will arrive right around the same time as New Super Luigi U. While not overly significant, it will allow for a couple of things.

Once applied, the update will allow players to purchase the New Super Luigi U DLC in-game – no trip to the eShop will be necessary. The patch will additionally add Wii U Pro Controller support, giving yet another control option.
