Bad analysis.
Microsoft is better positioned this time around than it was with the Xbox One, Harding-Rolls argues, because it has embraced a console gamer focus for the system, has invested heavily in its first-party studio system, will have a Halo game ready for launch, and is expected to sell the Series X for the same price as the PS5.
XSX at the same price as the PS5 would cut a lot more into Sony's sales than this analyst predicts.
I won't make a prediction about the two consoles myself, because some crucial information is still unknown, such as price. But if the two consoles had price parity, then Microsoft would do more than just slightly better than with the Xbox One.
