NCsoft mentioned that in order to maximize the graphical capabilities of Lineage Eternal, they will be upgrading to Unreal Engine 4. Taken together with their past announcement of a change in the project leader and the entire development team (after poor feedback from the first CBT), NCsoft announced this will delay the scheduled launch significantly (they will provide an update on the next beta test schedule in their next quarterly financial conference call 3 months from now).
This does not even cover the core design changes they will need to make to the game again in order to address some of the negative feedback from CBT participants.
