Well I haven't gotten hold of the actual game til Nov. 10th, I did however downloaded the demo game from the Japanese PSN (yes, you need a Japanese account but who cares). Just like the Project Diva 2nd demo last year, you'll only play 3 songs. If you haven't done so, I encourage you to download it for the previews till the game actually gets released. Here's a link on what the game play is like.
