"It's very interesting," said Matsuura-san speaking with . "We are thinking about ideas. I think any kind of interaction with a camera will be good for music games, but the important thing will be how we can find the new breed of gameplay. That will be a very important thing."
"Guitar Hero and Rock Band and The Beatles: Rock Band, is just taking traditional rock music. Of course there are so many rock fans on the earth, so they will have a huge impact for the market. But there is other attractive music, so please try to find another style, another interaction, another gameplay with another type of music," he continued.
