an image from a Chinese blogger who says he has himself a 3ds dev kit and a moc up by kotaku
the top screen is apparently where the magic 3d is and the bottom screen similar models of the ds
also it reportedly has an analog stick (im guessing that thing below the dpad) and may have a tilt sensor or accelerometer or somthing similar
