Yeah, I was looking through the ruliweb article after reading the article on Kotaku. It looks like:
Clazziquai Edition:
- Geared more towards the mainstream/casual audience.
- As such, the difficulty will be tuned more towards newcomers to the series.
- Doesn't seem like it will include the new features that are going to be in Black Square.
Black Square:
- Designed for returning DJMax Portable players. Leans more towards less mainstream/more underground artists. Many artists from the first two games may make a return (Ruby Tuesday and ND Lee are just some mentioned at ruliweb)
- According to the trailer posted at ruliweb (Which is the same trailer that's on the official site now), there will be the following features (Not sure which ones are new or improved, as the trailer only flashes these names):
New Game Modes, Expansive Fever System, Wireless Network Play, Dynamic Mission System, Advanced Album mode, Media Install Ready, Full Motion Video
- As JEKKI said, this one is likely to be considered the next main installment for the series, a DJMAX Portable 3, if you will, even though both of these new games are under the "Volume 3" label.
