There's also nothing in this that really needs Intel to do it, an OEM could easily push a SteamBox. I'm not an OEM, but there's no real hard work here afaik. Make good choices in hardware, test and confirm, put in good antennas so that wireless controllers (that are already in the marketplace) are rock solid. Do some support work, etc.
All current console CPUs are custom silicon, eliminating bits they don't need an adding what they do need.
Likely taking Panther Lake as-is would be too expensive.
