I was expecting Xbox Series X|S to outsell PS5 in the US. Mainly because the PS4 only outsold the Xbox One by 5 million in the US. And now this generation Xbox has more exclusives than with Xbox One.
The thing is, although Xbox One done surprisingly well in the US,a 5m loss is a lot. And thats a lot of users who would have been brought into the PS echosystem and may not have any reason to leave. When the tides change and favour one system, it takes more than just underdog to do well, it also requires the market leader to do badly. Stock right now is Sonys only major point. The exclusives from Xbox can make a difference but I don't think we'll be seeing the most important ones until generation is already on its tail end. Gamepass could be enough for some people to jump ship entirely but I personally wouldn't take that bet. It'll be a close one anyway
