this is not news, this "leak" was released days ago and as previously mentioned it's extremely doubtful to represent the final product (on Sony's side at least), if nothing else by the lack of hardware ray tracing which was officially confirmed by Cerny.
the more recent rumors talk about a significant architecture change that risks the holiday 2020 release. also, sony have been hinting some news at ces, so we should know more soon
on the xbox side it's looking pretty good performance wise, although 56 CUs will be a very interesting proposal when it comes to yields. it's a huge gamble, if amd can't keep high yeilds, the cost will be insane. unless MS is aiming to keep it pretty much a novelty product and only mass produce the lower end sku, it seems way too risky.
we'll see...
