Sega have launched a teaser website for something called Project 575, along with a teaser trailer for the same. You can visit the website here and watch the teaser below:
The song playing in the teaser video is by Vocaloid composer Lamaze-P. The character in red identifies herself as Masaoka Azuki, while the one in green is Kobayashi Maccha. Another rhythm game, perhaps?
