Michael Morhaime - Chief Executive Officer and President of Blizzard Entertainment - has announced that Blizzard has received, "approval from the (Chinese) government to release Hearthstone, which allowed us to go live with the open beta in China concurrent with the rest of the world," and that the dev team on Warcraft is being upped.
He told analysts, "In terms of World of Warcraft, we think that the ongoing engagement in the game really is just dependent on ongoing content, and we're continuing to invest in growing the World of Warcraft development team and creating new content."
"And really looking towards getting into beta on Warlords of Draenor, we think there are a lot of great features that will drive engagement with the game and hopefully bring players back to the game," he continued.
Finally, more good news for Warcraft is that it appears to have stopped bleeding subscribers. Activision states that, "Global subscribership in the quarter ended at 7.8 million subscribers worldwide, and slightly above where we ended Q3, meaning that the player base has remained pretty stable for three successive quarters."
