Blizzard Entertainment makes a mint from its World of Warcraft franchise, and the gaming giant has had an unannounced massively multiplayer online (MMO) role-playing game in the works for some time. But GamesBeat has learned that Blizzard has decided to push the reset button, according to a source familiar with the matter.

The team of 100 developers working on the MMO, codenamed "Titan," has been reduced by 70 positions, and Blizzard is reassigning those people to other work. Meanwhile, the core of the team will start over on Titan. The title is now not expected to be published until 2016 at the earliest.

In a statement, Blizzard spokesman Shon Damron said, "We’ve always had a highly iterative development process, and the unannounced MMO is no exception. We’ve come to a point where we need to make some large design and technology changes to the game. We’re using this opportunity to shift some of our resources to assist with other projects while the core team adapts our technology and tools to accommodate these new changes. Note that we haven’t announced any dates for the MMO."

Now that the project has been supposedly reset, it doesn’t look like it’ll be coming out anytime soon. Meanwhile, it will be a big test in the market for Blizzard to hang on to its World of Warcraft subscribers at a time when many other MMOs have gone completely free-to-play. Blizzard has held off on the free-to-play business model in favor of paid subscriptions, but it has made concessions, such as making the first 20 levels of the game free.
