You won’t be forced into the next generation. We want every Xbox player to play all the new games from Xbox Game Studios. That’s why Xbox Game Studios titles we release in the next couple of years—like Halo Infinite—will be available and play great on Xbox Series X and Xbox One. We won’t force you to upgrade to Xbox Series X at launch to play Xbox exclusives.
Curioso aí esse "next couple of years". Parece que a janela de jogos entre gerações vai seguir por um bom tempo.
Halo chega esse ano, então já seria um ano. 2021 mais um e pronto
