While I am not sure if the official English name will be the same, the Korean version for the much-anticipated game, Project R1, has been officially named as Tree of Savior (트리 오브 세이비어). There is currently no official image for the new name yet.
Hopefully, this will also mean that the game will finally make an appearance at G*Star 2013 this November. With development led by the “Father of Ragnarok Online”, Mr Hakkyu Kim, Tree of Savior is 1 game to look out for.
