According to Korean gaming news site GameFocus, NCSoft Korea is going to launch a couple new beta tests this year starting with another beta for the Korean version of Master X Master in March followed by Lineage Eternal beta in April. Better not get your hopes up though, they always say the same CBT for LE yearly.
There have been also numerous reports of Lineage Eternal launching this year, but to debunk that theory. I don't think that's happening anytime soon given the game has to undergo a bunch of CBT's usually in CBT1-3 and an OBT before release. Unless they go with the hype train of releasing games earlier than usual.
