Steam partnered with Chinese online shopping platform Alipay last week. A path of overseas gaming purchasing has been paved for Chinese gamers.
It's been a week since the partnership was forged in China, and many discussions are emerging on the internet, one of the most believable version is that this is the "prelude" for Dota 2's China launch. Months ago, there used to be a server set in Shanghai for Dota2's beta. Meanwhile many game companies have been fighting for the big title's license for a really long time, and various rumors about that have been going wide. But there hasn't been a clear confirmation yet.
