GTA coming to the DS

So the extremely popular GTA series is making its round to the handheld. It's coming out on the DS. I thought it's a bit strange to release GTA: Chinatown Wars on the DS. Maybe it's because of its wide install base. But I thought over 50% of DS owners are females?

I thought PSP would have been more appropriate. Strange, that. But I guess whatever float the boat.
