Ever since the announcement of ARMA 2 mod DayZ becoming its own Standalone game, we have not heard a lot of information about new features and the release date. Just recently Dean “Rocket” Hall, the original creator of DayZ, posted an update in regards to some new features that will appear in the new DayZ Standalone game. This update talked about new features regarding the lighting engine, a volumetric cloud system, new server architecture, art/world updates, as well as the ability to customize your character and even guns.
The blog post brings up the topic of when the game will be releasing. At the moment they are going to take it slow and see where the development takes them. There is no release date as of right now, and there are no hints as to when exactly it will be done.
