The news came via Twitter, and was appropriately to-the-point:
We’re pleased to announce that @Legendary Pictures’ WARCRAFT will be released by @UniversalPics on December 18, 2015.
This is the first concrete information we've heard about the film for months. Just last week, we heard rumours that Colin Farrell and Paula Patton were reportedly in talks for two major roles, but nothing had really been confirmed for the project since it picked up the award-winning Bill Westenhofer as Visual Effects Director.
San Diego Comic-Con attendees were treated to a "mood piece" concept trailer, where director Duncan Jones explained the project would be a blend of live-action and computer-generated effects, hinting that the traditional rivalry between Orcs and Humans will play a major part.
We are waiting (im)patiently for further news on the project - production is set to commence early 2014.
