China is also shown to be very amenable to having custom versions released.
If all they have to do is tone it down a bit, they will.
I've also heard more than once about China being convinced something isn't so bad with cash. Can't prove it, but I've heard it. So I wouldn't go laughing to the bank on the thought that Blade and Soul will be not even released there.
What is more likely is that it will, and has a chance of doing fairly decently. CoH will not be regained because B&S failed to see a release in China, and likely not because said game fails to engender money from MMO-goers.
Just to keep things appropriately realistic
