I don’t think it’s a death, it’s more of a transition. Firstly, a lot of XBox games have been coming to PC, intentionally, because Microsoft basically own the market*. They’ve also created XCloud + Game pass, possibly the most convenient way to play games, and you don’t need an XBox.
The real people who’ve turned on the device itself has been devs. Some of the stuff they’ve been saying at GDC have been at the same level as the stuff they say about Linux as a target. Like your game shouldn’t be that dependent on platform, it hurts things like archival.
