I think the chinese version just finished CB. To my knowledge, there isnt a korean version. The version thats farthest ahead is the chinese one, and the SG version is following close behind, as it is using the bug fixes from the chinese betas, to create clients for the english betas.
The game is currently in Closed Beta. Chinese servers are still recieving and finishing debugging there Build B update in Beta. And finally the Singapore (Iahgames) have just recieved there Build B update and is planning a Closed Beta Shortly.
UPDATE : After reading the BBS abit on the Korean website it seems there in Closed Beta.
They have been in closed beta for about... 10 months? I dont think so. Because i found a video demonstrating Closed Beta in December 2007. Oh it was Actually Alpha. But seriously. I dont think it takes that long to get past Closed beta and Alpha.
ehh playns is also doing punch monster.. which has been doing cb for a while.. i played but now i cant get in anymore.. says something bout cb not sure what.. and i played uhh 5 months ago? maybe more?(also hosted by plaync)
I think after the Alpha they really had to buckle down and redo some of the engine. (Build B of Dragonica for example). Well other then that, whining won't make it come faster.
Im keeping a close eye on both the english and korean version.. So Don't worrie I'll post RIGHT WHEN I find out its OB ;3 And any new good news comes up.
