Actually PWE China has hands on more than few things:
- They are working on their first Themepark/Sandbox hybrid, Swordman Online, which takes a lot from style of bioware games(npc interaction, multi-choice quests, relationship systems with npcs, AI for enviroinment) and is based on one of the most famous and awesome works of chinese literature, Smilling Proud Wanderer.
- They are planning to expand into the console content, with first targets being PS3 versions of Swordman and Empire Of Immortals. (altho this is till cloudy)
- They are working on major revamps/expansions of Battle of Immortals, Perfect World(the major thing being this Genesis thing) and ZhuXian/Jade Dynasty.
- They are also working on the first major expansion for Forsaken World
Now for PW:Genesis. Its not JUST "Expansion". its the "Cataclysm" of Perfect World. The Chinese expansion teaser website hints at graphical revamps of the whole world, major overhauls of various features, classes, skills and a lot of new content.
As I said , its the "Cataclysm" of Perfect World. The world is destroyed and reshaped and a lot of stuff changes.
