Source: Original Interview, English VersionApproximately how long do we have to wait until Tree of Savior Closed Beta Testing?
Closed Beta Testing should probably start in Korea this winter. (Winter starts in December in Korea)
Will the Closed Beta open to everyone or is there IP block for some countries?
This has not been decided yet.
Will Closed Beta require CBT keys or will it be open to everyone?
You will need a NEXON account. Whoever has it should be able to participate in the Closed Beta Testing.
It seems that the upcoming CBT might only be available for koreans. However it has not been officially confirmed by imcGAMES and might have been some misinformation of the interviewed imcGAMES employee. Nonetheless we should be prepared for a CBT that will only be available for koreans.
