To be honest, though, it is apparent that NCSoft could care less about NA and EU.
But isn't the GW series crazy mad popular in Asia as well? I seem to remember tons of Koreans overtaking the original GWs' PvP arenas back when I played it at launch. Now there would be your difference in the "caring" department for NC. I would think they'd do anything within their power to keep ArenaNet and the GW franchise.
Yes GW was localized for a variety of Asian countries including Korea, Taiwan, Philippines, Malaysia, Singapore, Thailand.
GW2 is now being localized for Asia, currently it's only available in NA and EU.
And while it's true that they are down to Lineage 2 and Aion in NA, and they aren't doing particularly well (seen any advertising for those MMOs in NA?) it is reported that they are revamping the missions in B&S to make the game more suited to NA and EU than a simple language translation. Don't know if this means less grindy, less team dependent, less PvP targeted, don't know I guess we'll see.
I think every MMO company would love to have a game that's equally popular in the East and the West.
