The problem I have with taking this leak for fact is that it is outdated, as DF says. For one, there is no mention of ray-tracing HW in the testing, even though that is confirmed to be there. And two, this actually lines up with a leak on pastebin from early 2019 that stated Sony was originally aiming for a release in 2019, supposedly using beefed up Jaguar cores and a 9.2 Tflops GPU. They got negative feedback from devs, so scrapped it in favor of a 2020 release, which the leaker rightfully claimed was using 8 Zen 2 cores and he said they were now looking to hit 10+Tflops with the GPU. We have heard 10+Tflops from other sources, as well.
As for price, I think we are going to see ~$450 from Sony, while MS shoots for ~$550-$600.
