So a lot of people say that the 65 thousand units sold for PS4 Pro in Japan are mixed numbers and like always the biased media tries to spin it around mocking how the NES mini has outsold it or how it sold as much as the PS4 Slim. But all of them are ignoring the elephant in the room, that this thing is completley sold out in Japan!

As can be seen from the biggest online retailer networks the PS4 Pro is supposed to cost 45,000 Yen ($408) but scalpers are charging around 55,000 Yen which which is around $500. Thats quite alot of resell value which we havent even seen during the PS4 launch worldwide. And more importantley the Slim can be bought for 30,000 Yen with plenty of stock avaible which proofs that the PS4 Pro launch cant be compared with the Slim launch.
You had so called sites like: ''PlayStation'' Lifestyle downplaying how Japan doesnt matter for the Pro (ps4-pro-japan-be-like-meh still in the URL) and other general assumptions from western gamers about Japan may they be upfront or subconsciously. But as you can see Japanese gamers love more powerfull hardware too.
PS4 Pro sold 65k units in 4 days and is completley sold out in Japan. It could have easily sold 90,000 units if a have a higher stock would be avaible in Japan like in other western countries where the PS4 Pro isnt sold out. So even Sony belived in this generalization and droped the ball here.
