The Witcher 3 is set to receive one more DLC as a part of its 16-free-DLC deal promised to players. This doesn't preclude its developers at CD Projekt RED from offering future updates and DLC.
The contents of the update were leaked on the PlayStation Store and Xbox Marketplace, allowing players to download the DLC, which brings a new look for Ciri.
Unfortunately, the DLC is incomplete and may cause problems with the game if you have it installed. The game's community manager advised gamers who downloaded the DLC to uninstall it. One person even responded that the DLC caused his save files to bug out, so be careful out there.
The DLC is set to come out after the developers have finished working on patch 1.07, which releases soon. The update is set not only to fix bugs but to add numerous features highly requested by players. Details can be found here.
