Famitsu interview

They say one of the reasons it's hard to add new zones is they are at/near the limit of how many zones the game is allowed to have, ID stuff?
However the game is very messy, and has lots of dummy zones / unused things and they think a cleanup will allow them to add new zones, after removing those from the database.
They say they have a proper engineer (coder) assigned, but he is currently being used mostly on playonline issues and so the other work they wanted him to do is "on hold" (blue stuff)
No idea what the playonline issues are.
