Hatsune Miku Project Diva Ver. 2.5 has that whole ".5" in the title, so it shouldn't surprise you that it looks just a little bit like Hatsune Miku Project Diva 2.

Project Diva 2.5 retains the basic rhythm gameplay systems of Project Diva 2, but adds refinements to improve the play experience. You'll find all the new gameplay features from PD2, including simultaneous button presses and long button presses.

The game also includes new music and Modules (costumes) created by famous illustrators. Sega shared just a few sample images today:

Hatsune Miku Project Diva 2.5 will be available for PSP this Fall.
