There will be NO WIPE at all. They are still sending CB invitations and I guess they will non stop sending until the server is full. Once they are happy with the current version from Valiant Force they will launch it globally with a new server. So nobodys will complain, new players will have their own fresh server and a version of Valiant Force improved, we beta testers had the luck to enjoy the game before than everyone else.
Beta players will find they are too advanced like to start from zero in the new server. Who wants leave his lv 50 accounts? Nobody.
So I guess the population from our Beta server, the first server somehow will keep healthy.
Clear as water.
