Hatsune Miku Project Diva Arcade game

Famitsu.com has revealed that sequel to the highly successful PSP Hatsune Miku game is going to be called “Project Diva ARCADE”, and Sega is going to be taking original song submissions for the game through niconico.
They will be taking submissions (original unreleased songs only) between the 15th of October to the 31st of October, and each song has to be approximately 3 minutes long. Songs that have been selected will be announced on the 16th of November, and the loketest will start January 2010.
Sega had announced a while ago on nico that they’re working on a sequel and will be taking submissions, but… an arcade game…?
