Wrath of the Lich King is coming ; Return or stay for Cataclysm?

"Wrath of the Lich King" is already available for download, and domestic World of Warcraft players will soon be able to enter the continent of Northrend. Although the Chinese server version of "Wrath of the Lich King" came "very late", it was eventually not "forgotten". As the Chinese server is about to launch Wrath of the Lich King (WLK), players are beginning to hesitate: Should I stay on the international servers and wait for "Cataclysm" in three months? Or should I return to the Chinese server and continue my journey in WLK?
