I think its early November
Yea you definitely need to pre-order if you want to get in the next previews.
I also heard a discussion on discord about it from the devs.
They couldnt even give keys to all the preorders the previous preview which made allot of them upset, so they said that all pre-orders will first be given keys, then non-pre-orders will get keys if there are any left.
But....looking at sale numbers....unless they are allowing in a few million players for next preview....there wont be any keys for non-preorders.
Just buy it.
soooo what about new world guild?
I think you really need to pre-order if you want to get into anymore previews.
I heard that on discord.
