That sounds like such an advantage over other xbox consoles to the point where it isn't even being put out on them, But unless they expect much faster load times than the Windows version, thats not the type of unique features I mean.
It thats the case then its just a poor fit for what I'm looking to see, and perhaps they will talk more about unique selling points later.
The unique selling point is that you get to play the "best" version of Microsoft's games without having to buy a high-end PC.
Not everyone has nor wants a gaming PC. Some of those people will be interested in at least one game that Microsoft shows. The Xbox Series X is for them.
This has been their official mission statement since Play Anywhere and the One X back in 2016/2017. Microsoft makes Windows so they don't really care if someone decides to invest in their PC instead. A PC gamer who buys a console purely for exclusives probably isn't going to dump much money into multiplats anyway.
