Around early February, it was reported that Wrath of the Lich King's Chinese release had been delayed. It was suspected that the launch was postponed until after the National People's Congress (NPC) and the Chinese People's Political Consultative Conference (CPPCC) which occurred in the first week of March, but things are starting to look a little bleak.
There are rumors abounds that Blizzard and The9 are having something of a falling out, but it's being reported that things are going much more poorly on The9's end. Specifically, they've hit some trouble with the censorship board. You might recall that China has some very, very strict rules when it comes to things like video games and movies. Many of the models in the base World of Warcraft game needed to be altered to conform to these rules, such as the exposed bones on the Forsaken and the bones left behind when a player dies.
