So Sony has shipped ~4.5 million PS5s in 2020. They only expect to get out about 16-18 million in 2021.
According to VGChartz, 53% are sold in the US, 40% to EU, and 7% to Japan. So best case 9.5 millionish would come to the US in 2021 if they kept the current split.
China being a HUGE market I would assume will land somewhere between EU and US in terms of demand. So lets for argument’s sake say that we take the 93% going to US/EU and split it 3 ways adding in China. Each region now gets about 31%. So now the US is going to be getting around 5.5 million PS5s this year. That sucks.
Get supply to the current regions before opening up to new regions!
