We got this same thread going on NA side so NA Rep should respond to this one with official info but thread was about new servers at PS3 launch + if they will combine servers for servers with few people.

本件、吉田Pと確認してきました。
Checked with YoshiP regarding this.

他のスレッドでも新サーバーの要望やサーバー統合の要望もお寄せ頂いていますので、それらも含めてプレイ状況やログイン状況などを見ながら随時検討・対応を行っていきます。
We have received other ideas from other threads as well regarding new servers or joining servers, so will correspond at all time looking at login status or play situations.
