I am not sure I believe MS would purposefully do this. I think at the end of the day I fully expect PS5 and Scarlett to have about equal power, maybe a very minute edge one way or the other (less than 10% advantage in GPU/CPU). That's assuming MS nor Sony are doing multiple SKU's at launch.
And one way or another, it's really quite trivial regardless. Sure, it's a neat line to throw in your ads to say you have the most powerful console on the planet or whatever, but at the end of the day, that doesn't mean a damn thing to anyone unless you have games that realize that in a meaningful way.
