The game news website 4gamer.net features today a very very long interview with the PSO2 main staff about how the project started, the reason why they decided to make a multiplatform game and many other interesting bits of information about upcoming updates.
However on the last page of the interview they talk about the release of the game in western markets and how they got shocked when they noticed that people really really wanted PSO2 to be localized to the english, they even mention the translation patch works made to the character creator and the game during previous betas and they couln't beleive the game was translated almost entirely in such short amount of time.
Therefore they mentioned also that same as happened with PSOBB and PSU the Japanese servers will be completely separated from the US/EU ones due to laws of each country, censorship issues, etc.
It's very unfortunate they decided this as I know many people here including myself was hoping for a true global PSO like the old ones from the dreamcast and the gamecube.
