Bless is still a long way away from any sort of western release no matter how its beta testing goes, seeing as it has no announced localization plans whatsoever. That having been said, the game is heading toward beta testing starting early next year, so if you're reading the site from Korea or are just deft at translation, you can look forward to that.
According to the development team, the plan is to open up the beta test toward the beginning of the year with a January-to-March test window. Barring unusual developments or unforeseen glitches, the game is also slated to launch by the end of the year. From what we've seen of Bless so far, it certainly looks gorgeous with a focus on story and endgame content. Only time will tell when and whether we get to experience it firsthand.
