If you buy Madden NFL 21 on Xbox One, you'll be able to play it on Microsoft's upcoming Xbox Series X as well, as revealed in Microsoft's Xbox 20/20 livestream Thursday. The cross gen compatibility doesn't appear to be part of the company's Smart Delivery feature, but a separate program offered by EA Sports and Microsoft.
You'll have to buy the game on Xbox One by Dec. 31, 2020, and upgrade to the Xbox Series X version by March 31, 2021, to take advantage of the offer.
