Xbox boss Phil Spencer told The Verge after the launch of Series X/S in 2020, that Microsoft manufactured more Xbox Series X consoles than Series S, but, there is also a steady stream of Series S consoles arriving on the market.
Microsoft has stopped manufacturing Xbox One S consoles in order to focus on the production of Xbox Series X/S.
The company stopped making Xbox One X back in July 2020, but Xbox One S manufacturing continued until the end of the year.
Spencer also recently stated that Microsoft has sold more Xbox Series X/S consoles than any previous version of Xboxes.
