Hatsune Miku on the way to Stardom

You know Hatsune Miku right? Well, she is planning to have a major concert in year 2009.
(LOL straightforward)
Well, actually, the makers of Hatsune Miku and with the cooperation of Sony Company(PSP) and Sega(I think), will make a song game called 初音ミク-Project Diva-(Hatsune Miku-Project Diva-).
If you know Beats game, Sony Europe game, then it will easy to understand how the game will go.
But not like Beats game, from the video I will put below, you can customize Hatsune Miku itself; from her house, her costume, and maybe colors.
