Blizzard's Project Titan continues to be shrouded in mystery. Last we heard, Blizzard was going back to the drawing board with its planned MMORPG, with "large design and technology changes to the game" cited as necessary. Significantly, it now appears Titan will not follow World of Warcraft's subscription model.
Blizzard's Mike Morhaime told investors (via Polygon) that "we're in the process of selecting a new direction for the project and re-envisioning what we want the game to be. While we can't talk about the details yet, it is unlikely to be a subscription-based MMORPG." MMOs have largely been unable to sustain a subscription model, with major launches quickly switching to free-to-play. Even World of Warcraft's subscriber count has been continuously dwindling.
Morhaime also reiterated that there has yet to be a formal announcement or projected release date for Project Titan, though it will retain Blizzard's "commitment to quality."
