Let's contextualise this.
In the past 9-10 months since the last E3, we've had a wealth of 'leaks' regarding the future of Xbox. Scarlet, Anaconda, Lockhart, Fall 2020 for Scarlet, Xcloud, platform strategy, Gamepass strategy, Maverick, Nintendo-partnership, acquisitions considered from a range of sources like Jez, Brad Sams, etc.
So much of these details have been proven accurate in the past few months to varying degrees with stuff like XBLive on other platforms, Cuphead on Switch, Xbox SAD, etc.
A lot of these details, imo - are clearly 'controlled leaks' seeded from MS themselves so that they are dictating the next-gen messaging even as they are 2 years out from the release of their next-gen console.
And purely by the logic that they have a 2 SKU strategy for next-gen ( Anaconda/Lockhart ), that imo is a very clear statement from MS's camp - they want to, just like current gen with Xbox One X and Xbox One S/AD, have the advantage from both power and pricing perspective. Where there are 2 SKUs to both have the claim of 'most powerful' and 'most affordable' at launch.
Will Anaconda actually be more powerful than PS5? Personally, I wouldn't immediately assume so. Still too early to tell without more details.
But I'm pretty sure that MS fully intends Anaconda to be the most powerful system it can be at whatever price-point that it aims for - and imo the only real question is "Did MS assume PS5 was gonna be a cheaper $399 console or something when it's actually (potentially) $499" and Anaconda was gonna be a $499 machine that was superior in the same spectrum of how X was superior to Pro with a $100 price advantage.
