There is no bias here, just the truth. That "competition" and severe supply shortages didn't stop the PS5 to break record and outpace the sales of PS4 worldwide. So much so that the PS5 already sits at around 30 million worldwide in about 2 years, but somehow Sony could only send 10k PS5 every week, because of "reasons". So while supply constrained, its not like they were making few consoles. Nintendo had similar issues but Japan never had an issue as bad as PS5 had of being sent basically nothing, because Nintendo values the japanese market.
So what happened? Simple: Whatever production Sony had, it was sent elsewhere, because they don't care about Japan. Now that elsewhere is well stocked, the countries that they deem secondary or terciary can be sent stock to.
That's just the raw truth. If you wish to see it or not, that's your problem. But I'll be here regardless discussing these stuff, because I find it engaging. Anyway, let's see for how much longer can Sony sustain this momentum, which is clearly being lead by 2 years worth of surpressed demand.
