It appears that the smart TV roll out will start with 2022 Samsung TVs on June 30th in 27 countries. Xbox will release its app on the Samsung Gaming Hub and you can either login with your existing Microsoft account or sign up for Xbox Game Pass Ultimate for $1 (for the first month).
You can then connect your Xbox controller or PS5 DualSense controller and play over 100 games from the Cloud without the need for a console. This technically means that you could play Fortnite on your 2022 Samsung TV without owning a console.
It’s unclear at this stage if the Xbox app will roll out to other Samsung TVs that weren’t released this year, or other brands such as Sony or LG, but it’s definitely a huge step in the right direction in terms of providing accessibility for more people to be able to play games.
