As large as the potential market of China is I think that a lot of people are putting too much faith in China. The sad fact of the matter is that China is not a stable market and so companies can have profit one year and be disappointed the next. Chinese regulations are so stringent that it is smart for any company to never put too many chips into the Chinese market because that could very well backfire. Most of what we've heard about China for the last two decades have been over estimations of that country's capabilities, on paper the economic potential is there. However in reality there are too many factors to take into account. For instance why does China only have 15 million Steam users when it really ought to have so many more? There is good reason to not make the Chinese your target audience. In addition to many factors such as piracy, the difference of the Chinese audience, government regulations of both foreign trade and their own citizenry it seems that no one considers things like GDP either.
