Given the amount of SAO/Mahouka cross-promotion which Bandai Namco have engaged in as of late, it would be ironic if Yuuichi Nakamura were to voice an antagonist to Kirito here, since Yoshitsugu Matsuoka also voices one of Tatsuya's most notable rivals over on the other side of the fence.

There is a section (marked "Topics") on the game's home page which lists which updates are posted on which date, while Dengeki Online have a SAO game news page which updates with new articles for Lost Song (and for other new SAO-related game works). Also, some of these updates have English-language articles posted about them on sites like Gematsu or Siliconera.
