I mean, I'm not suggesting a pro console. Closer to the Xbox One S if anything. We already know, despite the claims, that a mid gen refresh console was indeed in planning for MS as early as 2020 thanks to a bunch of unredacted internal documents MS accidentally posted during their anti-trust trial over Actiblision, it included things like a new case design, new controller, etc. So it was 100% coming, was a bigger change than the PS5 slim, and could/should still be scheduled for next year.
The thing is, they want to save money. Right now AMD can offer to move them to TSMC 4p, move them onto chiplet based PHYs, and maybe even disaggregate CPU/GPU onto chiplets. If you're doing all that anyway, you can move to GDDR7 and save a PHY or two in exchange for faster ram and probably get more cost savings over that time. If you're doing that, you can move from a 320 bit bus to a 256 bit bus, 28gbps ram, and then suddenly the option to overclock the GPU about 25% is right there, almost free.
MS would have to do almost nothing they're not nigh certainly planning to do already. It's not a pro console, it's just, a refresh, one that happens to save them money at the same time.
