I dont know why anyone would want to make or play any 3d racing games on DS, PSP games are just about bearable but 3D on a DS at speeds is just silly, why not have stuff in 2d! Might actually play well and be enjoyable, people (Me at least!) like the DS for its general playability and cool features, if I wanted to play something with really good graphics, like a 3D racing game! I would do so on my PC, PS2 or even buy a PS3 early - currently waiting for Metal Gear Solid 4 and GTA 4 are out though, hopefully price will have gone down and will get updated firmware or whatever other improvements might be made to the system.
