By the time "people start moving" the new Xbox will arrive.
From MS, the exit of Series consoles and/or contented profitable stagnation until the next console situation is clearly visible. They no longer care how many Series consoles sell (otherwise they would have brought a price cut). MS is already clearly looking at this generation as a kind of transition period until they launch their new, better-than-anything AI based console.
That would be such folly. Like, how on earth would they think that would work?
"Let's just keep making all our games playable on more popular platforms while bleeding market and mindshare til nobody cares about us as a hardware platform owner at all anymore, and then we'll come back with a new console and it'll go great!"
If they've really given up on this generation entirely and dont want to fight in the hardware market, they might as well not bother to ever release a new Xbox ever again. Seriously, it will just be an even bigger failure. All your initial and critical early momentum in a new console generation cycle comes from your level of success from the previous generation.
I mean, it would be the most ridiculous thing ever. "Hey everybody, check out our new best ever console. It does AI things! It's super powerful!"
"Do I need it to play any of the latest games?"
"Well....no, but it's really powerful! AI!"
"Nah I'm good, I'll wait for the PS6 so I can carry my PS4/PS5 library over and cuz it'll actually have next gen titles".
And it's not like Microsoft will have access to some special technology Sony wont. Heck, even in the AI world, they are seemingly ahead of Xbox in terms of like the single useful AI feature for gaming - reconstruction. Xbox cant win here. If they release a new console early like in 2026, it's just gonna get beaten badly in performance by a PS6 in 2028. And if they do a similar thing as with PS5/XSX where they launch at the same time as Playstation and have mostly the same tech, but just slightly better specs, it wont matter to anybody, as it'll provide such little tangible benefit, if any.
Their only chance was to actually make a fight of it this generation and try and regain some momentum, and they seem to be doing quite the opposite. They aren't giving anybody a reason to buy their consoles, so people wont.
