I'm not sure they changed the pinwheels. They basically gutted the whole sign and replaced both the screen and the ad panels above and below the old screen with one big screen. As most of these new displays are, it's obnoxiously bright and not all that much clearer. For me I still miss just having a large permanent sign somewhere that simply says "next home series" giving the team and dates.
