Not to sound like a hater but let's keep it real, Xbox One basically flopped...40M consoles compared to PS4's 110M and even the Nintendo Switch outsold it already despite coming out 3 years later. It has very few exclusive titles to speak of, at least ones that are acclaimed by critics/users. MS is yet again forced to rely on old IPs (i.e. Halo 6, Gears 5) instead of innovating, and their attempts to innovate are met with little interest and poor reception.
Then the Xbox Series X reveal and its "gameplay" demonstration hastened the end to whatever hype was left for it. Even if Halo Infinite looked polished and didn't need to be pushed back to next year, there are almost no other upcoming Xbox Series X games that people are looking forward to. Yes I know some of you will point out "Well I'm excited for this game" "I look forward to that game" I'm sure you do, but there are still very few games that have a ton of people hyped for, and not nearly as many as the dozens of PS5 titles that are already building immense hype.
I'm hardly a Playstation shill or fanboy; even compared to Nintendo, Xbox is falling behind in exclusive games and units. Even compared to its preceding Xbox 360, which I owned, Xbox One sold HALF as many units, most of which rode off the success of the 360. But since Xbox One was hardly a success, Xbox Series X has little inertia to carry it. So honestly, is there ANY real hype for the Xbox Series X? Will it sell half as many units as the Xbox One did, or about 20M in its lifespan? Seriously, you never really hear people talking about its games or release date or when they'll get to pre-order it. I've heard plenty of that for PS5 though.
