That's only if someone thinks that the GPU is the most important part. What Cerny described regarding the SSD is a paradigm shift. I don't understand people that prefer a new generation that's only evolutionary. Don't you want games that are fundamentally different design wise? Also people keep mentioning GPU power as a metric of how much a company has invested in development. That's objectively false. A component being weaker doesn't mean that a company failed but that it has different goals to achieve. If Sony thinks that sacrificing GPU power will give them a revolutionary SSD solution (while keeping costs low) then that's what they should do.
Comparisons to the Xbox One/PS4 are also false since the Xbox one managed to have a similar BOM without ANY superior hardware features. That's not the case with the PS5 and actually I'm not even convinced yet that it's overall "weaker" as a solution.
I know the SSD is amazing and all, but in the end of the day, multiplat titles will probably just aim to the Xbox solution. So what? The PS5 loads the game 2 seconds faster, but outputs worse graphical fidelity and resolution? Maybe lower FPS as well? Great! I'm sure people will gonna do loads of stuff with those extra seconds on their lifes while wondering why the new COD, Battlefied or AC runs better on the Xbox.
I know they had different goals and that's what I find baffling, after the PS4 being a straight forward piece of hardware.
Maybe they simply tried to design around the $399 price, and that's fair enough. But if that's your main objective, you should just start the presentation with this: it'll cost $399, so people at least temper their spectations.
