It's hard to make any definitive statements on the state of the sales race between PS & Xbox for this generation because it's still more of a supply issue than a demand issue. But once the chip shortages are over and the Series X|S starts to really benefit from MS's various acquisitions, I think we should see a very close race. It wouldn't even surprise me if the Series X|S squeaked out a narrow victory in the U.S.
Very close race? You mean NA market right? Cause, I doubt the difference is less than 3:2 in worldwide sales.
Only NA, yes, it will probably be close, maybe the Xbox will even get an advantage, unlikely but possible.
Prediction: In 5 years Nintendo will Lauch a "Core Mario game" very similar to Astro Bot. That said, many will Ignore Astro Bot existence and say Nintendo created this concept.
