Dual Entitlement lets you buy a game on one console, then receive the rights to play that game on both your current console and a new console. You'll get the right to download and play Madden NFL 21 on your PS4 or Xbox One, as well as the right to download and play it on a future PS5 or Xbox Two.
You can lose Entitlement by refunding a digital game you bought for full price, but only if you've played.
