XSX/S is having stock issues tooBrutal stock. But then again it was the biggest console launch of all time. Switch, DS, PS2, PS4 nobody matched the mighty power of the PS5. So Sony were too stretched and couldn't provide anymore to Japan.
They didn't need to however as their main rival has sold 8 times less. It's over already the war has been won. 2 gens in a row Sony have taken back japan!
