PS5 is basically tied within statistical tracking noise with PS4.
It was already well known to those who followed leaked NPD datas and shipments but some people had to cling to whatever doubt there was.
Demand for PS5 is far higher than demand for PS4 back in 2014 and that's with a main SKU costing 100$ more.
Like I've said, PS5 is on track for 200 million sales.
