Vocaloid idol Hatsune Miku has been in video games before. This year she will star in a PSP music/rhythm game developed by Sega. Hatsune Miku: Project Diva was announced with a trailer where Hatsune Miku sung and shooting star notes flew over her. The important bit of information Sega didn’t tell us was the release date. Sometime in 2009 is a huge release window.

Sega covertly announced Hatsune Miku: Project Diva will be in stores on July 2nd and cost 5,040 yen ($51). That’s the same price Namco Bandai’s Idolm@ster SP games go for in Japan. I wouldn’t expect Sega to sell Hatsune Miku: Project Diva for that much over here, but then again I wouldn’t expect this to get an international release. Good thing the PSP is region free!
