It seems not many people are on these days. Not surprising as I have been buys myself lately.lol
Anyway, here are some images I found for project diva 2nd
(Tentative box art)

As shown in this image the psp sequel will add the D pad to the mix. This means you will have to work with your other hand in this game. Making the game play more challenging. Now they can though 8 possible buttons at you instead of just 4 like in the 1st game.

An all new duet mode lets 2 vocloids sing together. I don't know if they plan to allow for more then 2 singers though.

Of course Miku is getting even more costumes in this game.

I guss I did something bad. I told Miku she would have to wait until July 29 to get this game and she started throwing a tantrum. She really want's it NOW!

Calm down Miku, you will just have to be patent. Being upset won't bring the game out any sooner. Besides, would you not rather wait and have the game done right then pushed out early and get it with a lot of annoying glitch'y bugs.
Also, if anyone else find any new images or information feel free to replay here. That is the point of thins thread after all. I hope we get some more discussion. Especially as the sequel gets closer.
