Xbox will be more powerful than PS5 for sure, but the difference will be far less then PS4 to Xbox One (38%) or PS4 Pro to Xbox One X (42%) in terms of Teraflop. PS5 to Xbox X are around 30%. Not include similar bandwidth and faster SSD speed on PS5 , it will be even difficult to notice even for a hardcore gamer like me. Digital foundry will be very super important on next year.
I also need to address the leak. The info spec are from Github and it's a a very old from 2018 , probably both already changed the spec or improve , because PS5 are already confirmed to have Ray Tracing and none of the leak mentioned this. So i guess it's just test for very early devkit. So it still not a confirmation.
But if the spec ended up like above
I can see Xbox X around 500 to 600 USD
PS5 around 400 to 500 USD
Xbox S 300 to 400 USD
Zhuge X from Era estimate that Xbox Series X spec cost around 520 USD and above. Also with having two SKU it will be difficult for Microsoft to produce and manage supply and difficult for Microsoft to lower the price. So i believe Microsoft strategy will go with Xbox S fro price and Xbox X for powerful/Expensives/Super niche.
Sony strategy will be one SKU with targeting balanced of power and price (similar with PS4/PS4 Pro)
Most Playstation gamer will be buy PS5 for sure and probably long time Xbox fans finally will returned to Xbox. I can see a good future for both, the problem is PC gamer , they will just stick to PC (because Xbox games are on PC) and casual gamer will just go to the most popular one A.K.A Playstation or stick to smart phones .
But if Microsoft good at marketing and gamepass really sell, some of them will buy Xbox S as alternative. But that also depend on what Sony might bring to new service. Sony might come to new tactic to counter Xbox game pass .
Another problem is launch title , Microsoft will be ready probably another 3 or 4 on making new ip with their new studios , while Sony are saving a lot to surprise with memorable title and ip and some new ip from Sony famous studios next year.
For me i will stick to PC, Playstation and Switch . But if Microsoft offer a good exclusives on Xbox and not releasing on PC i might consider Xbox X.
