There is a career page for Blizzard Entertainment. The mysterious project known as Titan used to have job listings there. Now there is no mention of Titan on this page.
Here is another fact: The man up there represented the beginning of Blizzard's cinematics department. This picture has nothing to do with Titan, but it amused us to include it.
What does this mean for the project? There are many possibilities: Blizzard is abandoning it, Blizzard has enough people working on it already, or Blizzard is regrouping on it. Considering that the studio said back in May that it was scrapping its development on Titan to start over, we think that the latter could be quite likely.
