A portion of a Siliconera interview with David Young, Associate Public Relations Manager...

S: Is Nintendo working on any DSi enhanced games in house?

DY: Certainly, were going to be seeing a lot of things coming out, but nothing we’re talking about yet.

S: Rhythm Heaven which launches tonight with the DSi comes from Nintendo’s Japan team. There are lots of other Japanese games like Soma Bringer and Archaic Sealed Heat also from Japan. Does Nintendo have any plans to bring those over?

DY: Those decisions are made by the parent company — which games are going to be launched in which different region. I certainly have a list of favorites myself that I hope to see someday, but it’s really out of our hands at Nintendo of America.
