FP32 performance of a M2 Max silicon that start at more than 2K is less than the 500$ Xbox. Developers see that if someone has that much money to spend on a machine so uncompetitive performance wise, they should have money for a console. They wouldn't be able to give a better experience on the Mac anyway, because of hardware limitation. PC's on the other hand can buy GPUs that crush anything even at the low/mid range (300$) ; and they can expect the system to be supported for years. It's a no brainer really.

Unless mac users go out in numbers saying they want to pay triple price for games I don't see anything happening.
