It looks like a PS3 game; it sounds like a PS3 game... But it's not quite a PS3 game. This upcoming "Dreamy Theater" is just a downloadable thingie from the PlayStation Network, adding PSP-to-PS3 connectivity to SEGA's rhythm game
Hatsune Miku: Project Diva. Players will thus be able to enjoy
Miku,
Rin and Luka in high definition, not simply up-scaled, but fully re-rendered in finer detail, once Dreamy Theater is released this June 24.

You'll find some pictures of it on the official
website, and if you think it looks like a worthy investment, know that this DLC pack will cost 3,000 JPY (a bit over $30), and obviously it will require the original Project Diva PSP game. Anyone still thinks it's a worthy investment?...
On a closely related sidenote, we also have this fresh
opening trailer for SEGA's sequel game
Hatsune Miku: Project Diva 2nd, which is currently planned for release in Japan on July 29, 2010. Still a PSP exclusive; still no genuine Miku game for a more powerful console.
