Blizzard Cancels Titan Project
You might recall that Blizzard "reset" the Titan project back in mid 2013.
Mike Morhaime confirmed to Polygon today that the project is now cancelled.
The team set out to make another amazing MMO after World of Warcraft, but
they didn't find the fun or passion.
Metzen said the decision to cancel Titan was excruciating, but cancelling
projects has always resulted in better quality work.
Right now Blizzard doesn't want to spend time working on another MMO.
Hearthstone and Heroes of the Storm helped Blizzard realize they don't have
to work on giant projects.
However, it doesn't mean that the development team is no longer working on
something. Multiple sources who seem to point towards a new unannounced
project from Blizzard that would be codenamed Prometheus and could be another
project built around a new license for Blizzard.
Keep in mind that this last bit is very much unofficial and unconfirmed.
