Xbox gaining high percentage because they sell 100x less units than Sony.

From that famitsu issue:

Hardware Sales (followed by lifetime sales)

Switch 2 – 59,543 (5,011,059)
PlayStation 5 Digital Edition – 12,141 (1,248,515)
Switch OLED Model – 7,468 (9,526,329)
Switch Lite – 4,807 (6,903,964)
Switch – 4,067 (20,0271,045)
PlayStation 5 Pro – 840 (341,548)
PlayStation 5 – 558 (5,910,474)
Xbox Series X – 525 (325,952)
Xbox Series X Digital Edition – 278 (29,362)
Xbox Series S – 129 (341,622)

So, PS5 digital non pro sold 12k units while the equivalent Xbox digital non pro sold 120 units.

If next month a Japanese retailer does a clearance sale and sells 200 Xboxes the headline isn’t “Xbox got a massive 100% increase in sold units in Japan, while Sony tumbled 2%”
