According to Sega's official website recently, Phantasy Star Online Version 2 was set to ship in North America July 10. However, Sega has since said that the information is incorrect, as they haven't made an official announcement on PSOv2's release date. In fact, Sega itself is still determining the release date, and hopefully we will hear an official announcement soon. This doesn't necessarily mean though, that PSOv2 is going to have a major delay, or much of one at all.
At this time, there is still no new information on the monthly fee for playing PSOv2 online. Keep checking back to RPGFan for new details!
