Echo of Soul: The Blue looks like it is coming to the West thanks to gamigo. According to a report on MMO Culture (via South Korean media), the European MMO company has re-signed the MMORPG's publishing rights, paving the way for a launch in the West.
According to the reports, EOS Blue's publishing rights allow it to be launched in North America, Europe, Turkey, Russia, South America and CIS countries. Echo of Souls: The Blue is a revamp of the original titale developed by Korean developer Blue Potion Games, and isn't to be confused with the version of Echo of Soul on Steam at the moment.
While we don't know when this could be coming to the West, it could very well be on the way now thanks to the publishing deal with gamigo. What this version means for the other versions, though, remains to be seen.
