Assuming 2 minute and 20 second headway between Rosslyn and Stadium - Armory and between Grosvenor and Silver Spring including the completed Silver line using all 8 car trains on all lines during peak plus 20 percent spares WMATA would need a fleet 1,888 cars.
Not that I don't love the idea of all 8-car trains at 2.x-min headways, but doing anything like that will take years. Not to mention, the current plans call only for an estimated 506 8000-series cars to replace the 366 2/3Ks + 140 for growth by the end of 2024 to have 1622 cars by 2025.
