You will have the chance to reserve your name, and perhaps also exchange your crystals for Tria (PlaneShift currency). Characters will be wiped, however, and will need to be recreated.
To put it more clearly: Yes, all characters will be reset, but you will be able to save your name and your money. When creating a character in CB, you will be able to \'unlock\' your reserved name with a password or something similar. Nobody else will be able to take the name unless they somehow unlock it (which can then easily be reported as a hack and get them banned).
That is how I understand it at the moment. All decisions on reservations and money transfers are subject to change at any time.
