The big question is:
Will there be the announced wipe on release Date?
And we have an answer!
but there will be a new official, well secured Server Cluster Network and the old Servers will be renamed to Legacy Servers. This servers, old and new ones, will be in different network clusters, so they´re separated from each other.
Ghost Servers with a player population near-zero will be wiped (around 10% of the servers on all platforms). (you can go to a secure Legacy Server with Cross-ARK.)
