Sure, but we’re talking about a handheld. Yes, performance is improving generation over generation, but in the handheld space power usage and heat dissipation are equally important. If you’ve been keeping up with recent innovations, you’ll see that generally we are making more powerful parts, but they’re getting much more power hungry for every little percent of improvement they bring in raw horsepower. So far it doesn’t look like you could even get Xbox series S performance in a handheld yet. At least not at a reasonably portable size, cost, or battery life. You could get a little better than PS4 pro performance in a handheld at present, based on what I’ve seen. Which is not a full generational leap over what’s out there.

If they released one NOW they’d probably be shooting themselves in the foot. At best they’d get mid-generational performance improvements whereas likely in the next year or two Valve is probably going to drop a true SteamDeck 2 with significant improvements. All speculation at this point, but if you’re a bean counter at Microsoft, speculation is like 90% of your job. Unless they abandon the standard console release cycle and shoot for faster iteration, they’ll want to come out absolutely swinging to compete.
