The rumor supposedly comes from a leaked internal memo to The9 employees, which says that an unnamed company (supposedly Netease) is trying to pick up the rights and hardware for the game for a cool $22 million. The9 reportedly paid $73 million for the same capability, so they're losing twice on the deal -- both the license and the money they spent on it.
Not good news for The9 if it all turns out to be true, but maybe this means Chinese players will get their expansions a little sooner. Of course, a lot goes into releasing new content overseas (translation is definitely not a small part of it), but having a more capable operator probably won't hurt.
Update: Confirmed. Thanks for playing, The9. Their stock is down big time since the announcement, and Netease's is up.
