Sega is working on even more Hatsune Miku: Project Diva downloadable content and their Dreamy Theater add-on is neat. This pack allows you to play Hatsune Miku: Project Diva with a PS3 controller on your TV.
PS3 controller support sounds similar to what Sony did with Resistance Retribution, which was released last year. Hatsune Miku: Project Diva’s Dreamy Theater has another addition – it outputs the PSP game directly on to a TV without a PSP to TV cable. The Dreamy Theater add-on appears to update the graphics too.
