The announcement came from a blog post at the official Darksiders website. A Q&A was also published in order to give fans more insight on the situation. A couple statements include that the delay was not due to the Wii U development of the game or due to the recent layoffs at Vigil Games. And further ensuring that this delay is primarily for making the game better and that fans can expect a more specific date to be announced soon.
This is great news for the team at Vigil, because it allows additional time for polish and to ensure that all aspects of Darksiders II meet the high-quality bar the team is targeting. In game development, more time is always a good thing for quality and the Vigil team is dedicated to providing the definitive Darksiders experience.
