I dunno. I think people are underestimating Phil's own words from just 3 days or so ago: "Our goal has always been to build the most powerful console we can, and i think we're there. We like leading in power and performance and i feel like we're going to be there again".
The fact that Xbox Xeries X needs a PC-like tower design to cool,i can't imagine PS5 being more powerful with out being even bigger and costing more.
This is not another Xbox One scenario where power was never the main goal.
Will be fun to see how this pans out.
