Starting to question my Series S order. Not sure it was the right choice. Immaterial really, as there were no Series X available when I ordered. But I'm tempted to cancel and wait for the X to become available.
The main driver here is backwards compatibility. Presumably Series X is getting all the same enhancements as Series S, but applied to the "One X Enhanced" versions of games (where available). Plus, having a disc drive opens up the possibility of grabbing cheap old games from CEX etc.
I'm also looking ahead to the game's coming out over the next few months, and finding I want to play Cyberpunk, Valhalla, Legion, Fenyx Rising, SW: Squadrons. Probably others as well, but these are the big ones. None of them are on Game Pass. Buying the games on disc and selling them on when completed could save a fair wedge.
