The biggest selling point we can see is the aptly-named Stylus Precision Handling (SPH). There isn't much of an indication on how this will work, and the touchscreen images in the gallery display only a map. Moto Racer DS supports up to 8 player Wi-Fi races, and features 44 tracks in a variety of road and dirt racing. That's quite a hefty amount of content, and we're hoping for a solid experience when it comes out in Q4 this year.
