The problem of metal-insulator transition (static Anderson localization) is reviewed from the viewpoint of random matrix theories (RMT).We examine the recently developed novel idea that in 3-d metals level attraction takes place that characterizes the transition, as mani-fest in comparison of the long-range (number variance) statistics for metallic, insulating and the mobility-edge states in thermodynamic limit.Their universal nature is shown in the same context as the semiclassical limit in quantum chaos theory that predicts the disappearance of non-universal saturation behaviors.
