A special event called "Perfect World 2 Carnival 2019" will be happening in Changlong, Guangzhou on October 19th. The event's main focus will be celebrating Perfect World's 14th anniversary along with its many players. At the same time, there will also be a competition called "Competition Masters" happening on the event, with live broadcasting of fierce battles between players.
The most important part of the event though will be the Q&A session with the game developers, which they will be unveiling their future plans and direction for the game, as well as explain the details of the game's upcoming expansion.
Hopefully they'll confirm my hypothesis that PWM is just testing grounds for a graphics/mechanics update for PW2/PWI in PC.
