Saying what you said is making a prediction. That's fine to do so, but we simply think it is too early to make some of those calls. Without a line-up, release date, or price, it's throwing honey hoping it will stick to something. Some of those very same proclamations were made at the beginning of this gen and that's why it makes more sense to wait until things have begun to happen.
You made a prediction, which is fine, it's just that we don't even know how much XSX or PS5 will cost or how their libraries will shape up so at this point I'd say projecting an XSX win in America is premature in my humble opinion.
Talking about the probability of something to happen isn't the same thing as making a prediction. Considering that the Xbox One is only ~5m behind the PS4 despite all the fumbles that Microsoft committed, an XSX that is equally priced to the PS5 has a higher chance to beat the PS5 than vice versa. The statement and reasoning are completely sound.
