I know there has been a desire for us to open a test server that players can use, and that echoes comments that Yoshida has made in the past. We feel that getting a test server implemented as soon as possible is necessary, but a large amount of work by the dev. team as well as fixes to the server would be required to make this possible, so the opening of a test server will begin post launch of 2.0.
In the meantime, we will work hard to provide as much information as possible regarding adjustments and additions going forward to keep you all as up-to-date as possible.
