I'm not too surprised, DQ is huge in Japan, they have to release the games on weekends cause if they release a title on the weekday people call in sick to sit in line for hours to get a copy.

The DS is also one of the best selling gaming systems of the last decade and almost everyone in Japan seems own one. Really combining a popular franchise with a popular console seems like a no-brainer.

I'm more surprised DQ X was announced for the Wii to be honest; but the Wii needs better third party support so god knows I'm not complaining.
